What field would you use to store a value from another table?

A. Lookup
B. Hyperlink
C. Memo
D. AutoNumber

Answer:

b. []

Explanation:

Arrays are represented using [] . When a method returns an array reference, the method header contains an entry of the type <data-type>[].

For example, a method test which returns a reference to integer array and takes no parameters is of the form:

int[] test();

Similarly a method list_chars which takes a String as an argument and returns an array of chars has the form:

char[] list_chars(String s);

Answer:

a. True

b. False

Explanation:

Constructor is used to initialize the object of the class.

Rules of constructor:

1. Constructor name must same as the class name. it means, if the class name is animalType, then constructor name must be animalType.

2. Constructor does not have any return type. it means, it does not return anythings.

Therefore, part (a) is true,  Constructor name must same as the class name.

and part (b) is false, because constructor does not have any return type.

Answer:

void print_popcorn_time(int bag_ounces){

   if(bag_ounces < 3){

       cout<<"Too small"<<endl;

   }else if(bag_ounces > 10){

       cout<<"Too large"<<endl;

   }else{

       cout<<(6 * bag_ounces)<<"seconds"<<endl;

   }

}

Explanation:

The function is the block of the statement which performs the special task.

For checking the condition in the program, the if-else statement is used.

It can check the condition one or two but if we want to check the more than two different conditions then the continuous if-else statement is used.

syntax of continuous if else:

if(condition){

statement;

}else if(condition)

statement;

}else{

statement;

}

In the question, there are three conditions;

1. bag_ounces is less than 3

2. bag_ounces greater than 10

3. else part.

we put the condition in the above if-else statement and print the corresponding message.

Answer:

def print_popcorn_time(bag_ounces):

   if bag_ounces < 3:

       print("Too small")

   elif bag_ounces > 10:

        print("Too large")

   else:

        bag_ounces = bag_ounces * 6

        print(bag_ounces, "seconds")

Explanation:

def print_popcorn_time(bag_ounces): #fed function

   if bag_ounces < 3:  #1st if statement

       print("Too small") #print function

   elif bag_ounces > 10: #else if

        print("Too large") #print than print

   else:  #else:

        bag_ounces = bag_ounces * 6 #do work

        print(bag_ounces, "seconds") #print

Answer:

Reference

Explanation:

The Reference type variable is such type of variable in C# that holds the reference of memory address instead of value. Examples for reference type are classes, interfaces, delegates and arrays.

We can pass parameters to the method by reference using ref keyword

It’s mandatory to initialize the variable value before we pass it as an argument to the method in c#

For example,

int x = 10;  // Variable need to be initialized

Add(ref x); // method call

If you pass parameters by reference in method definition, any changes made to it affect the other variable in method call.

Here's a sample program:

using System;

namespace ConsoleApplication

{

   public class Test

   {

       public static void Main()

       {

           int i = 10;

           Console.WriteLine("i=" + i);

           Add(ref i);

           Console.WriteLine("i=" + i);

           Console.ReadLine();

       }

       public static void Add( ref int j)

       {

           j = j + 10;

           Console.WriteLine("j="+j);

       }

   }

}

Output:

i=10

j=20

i=20

The simplest statement you can use to make a decision is the if statement. Thus, option C is correct.

A statement within a programming language is just a syntactic construct of an arbitrary programming language that also expresses a course of action. A series of one or more statements make up a program built in this language. There could be internal parts to a proposition.

The simplest illustration of a decision framework in Java seems to be the if statement. A conceptual test that can result in a positive or negative outcome is expressed in an if statement.

The if statements inside the if the branch were carried out if the test's outcome is true. In this case, the statement can either be true or the statement can either be false depending upon the condition.

Therefore, option C is the correct option.

Answer:

Procedural abstraction is a method in which all sub tasks of a whole functionality must be created separately as method and each method/ procedure must be performing a distinct functionality. For example if we want to write a program to calculate and display result of students in class and create separate methods to get students record, to calculate grades to display results is a procedural abstraction approach. Here not only the methods created have distinctive function the administrative can vary the level of abstraction as well.

It is important in computer science for the following ways:

1) Increase the level of code readiness as all separate functionality tasks will have a separate methods.

2) Prevents unauthorized of data.

Explanation:

Class Diagram is used in software engineering to represent:

- classes

- attributes

- methods

- relationship between classes

It provides a representation of the static layout of the application in object oriented design. It does not provide method implementation details. In fact code skeleton can be automatically generated from class diagram using appropriate UML tools.

Answer:

The function prototype is the part of a function definition that shows the function name, return type, and parameter list.

Explanation:-

In general we write a function definition as:

return_type function_name(parameter list)   //this is the prototype

{

    //function body

}

Final answer:

The term that completes the student's sentence is 'function header' or 'prototype', which includes the function name, return type, and parameters. It is essential for understanding how to use the function and what to expect from it.

Explanation:

The blank in the student's question should be filled with the term function header or prototype. This is the part of a function definition that shows the function name, return type, and parameter list. The function header specifies what the function is called, what type of data it returns, and what arguments it takes. The structure of the function header can vary between programming languages, but generally it includes the function name, followed by parentheses that contain the parameters (or arguments), and prefixed by the return type.

For example, in the function definition of int main(), 'int' is the return type indicating that the function will return an integer value, 'main' is the function name, and the empty parentheses indicate that this function takes no arguments. In another example, a function named 'f' might take three arguments - a, b, and c - and work with them internally to produce a result.

Understanding the function header is crucial for programming because it allows you to know how to properly call the function and what kind of data to expect back from it. Creating clear and concise function headers makes programs easier to read, understand, and debug.

Answer:

Argument

Explanation:

The function is the block of the statement which performs the special task.

when we define the function in the program then we have to call that function.

the syntax for defining the function:

type name(parameter_1, parameter_2,...){

    statement;

}

the syntax for calling the function:

name( argument_1, argument_2,...);

Meaning of parameter and argument

The argument is used to send the value into the function definition. this can be passed by value or pass by reference.

The parameter is used to receive the value send by calling function.

Therefore, the answer is the Argument.

Answer:

name(argument_1, argument_2, argument_3,.......);

Explanation:

The function is a block of the statement which performs the special task.

Syntax for calling the function:

name(argument_1, argument_2, argument_3,.......);

we write the name of the function and passed the arguments.

we can pass any number of arguments with separator ',' in the function calling.

for example:

1. print(name, value, count, a, b);

2. print(name, value);

Here, name, value, count,a and b are the arguments of the function.

if we does not pass any argument, the function still valid in the programming.

we can pass from Null to any number of argument.

Final answer:

To use multiple arguments in a method, separate them with a comma within the method's parentheses. This approach enables methods to perform more dynamic and flexible operations with variable inputs. An example includes a method to add two numbers, defined with two arguments, which are supplied in the same order when the method is called.

Explanation:

Using multiple arguments in a method allows for more dynamic and flexible code, enabling the method to perform tasks with variable inputs. In programming, a method can be understood as a set of instructions that performs a particular task. Arguments are inputs you give to a method so that it can perform its task with specific data. To use multiple arguments, you simply separate them with a comma within the parentheses of a method call.

For example, if you have a method designed to add two numbers, you might define it as follows: add(int num1, int num2). Here, num1 and num2 are the arguments. When calling this method, you would provide two numbers as arguments like add(5, 7), instructing the method to add 5 and 7.

In more complex scenarios, such as in object-oriented programming, methods might require multiple arguments of different types, such as strings, integers, or even objects. This variety allows developers to construct highly customizable and efficient code. For instance, a method for creating a user profile might require several arguments such as name, age, and email address: createUserProfile(String name, int age, String email).

When designing methods that accept multiple arguments, it’s important to consider the order of arguments, as they must be supplied in the same order when the method is called. Additionally, leveraging method overloading - defining multiple methods with the same name but different parameters - increases flexibility and readability in how methods can be used with varying arguments.

Answer:

throw and throws represent different constructs in Java programming language.

Explanation:

throw is used to explicitly throw an Exception from within a code segment.

For example:

public void throw_test(String str){

        if(str==null) throw new NullPointerException();

}

throws is used to specify an exception list which may be thrown by a method:

For example:

public String readFromFile(File f) throws IOException {

.....

// Some code fragment which could throw a IOException

}

Answer:

The size of the array is dependent on the amount of memory the program can access.

Explanation:

Here according to the question the user is in need of memory space equal to the amount of numbers read from the list. So the size of the array should be equal to the total numbers read from the list. if the user reads 5 number from the list then the size of the array should be int a[5] if the numbers are integers. Wastage of memory space is not appreciated in a good piece of code.

Answer:

Call showValue (12)

Explanation:

The function is a block of the statement which performs the special task.

if you define the function, then you have to call that function.

Then, program control moves to the function and start to execute otherwise not execute the function.

the syntax for calling the function:

name(argument_1, argument_2,....);

we can put any number of arguments in the calling.

check the options one by one for finding the answer:

Call showValue( Integer): this is valid calling but it passes the variable, not the 12. this is not correct.

Call showValue( Integer 12): This is not valid calling, because it passes the data type as well which is incorrect.

Call showValue( Real): this is valid calling but it passes the variable, not the 12. this is not correct.

Call showValue (12): this valid calling and also pass the value 12.

Therefore, the correct answer is option b.

Answer:

Using the Selection Sort algorithm there will be 5 swaps in total within the vector of ints.

Explanation:

A Selection Sort algorithm compares the first value in the vector with the rest of the values and swaps it for the lowest value. It then moves on to the next value in the vector and repeats the process until the whole vector is sorted.

Initial Vector : 6 7 5 9 1 3 2 4

1st Swap :   1 7 5 9 6 3 2 4

2nd Swap:  1 2 5 9 6 3 7 4

3rd Swap :  1 2 3 9 6 5 7 4

4rth Swap:  1 2 3 4 6 5 7 9

5th Swap:   1 2 3 4 5 6 7 9

After the 5th Swap the Vector is completely Sorted.

int to_the_power_of(int first, int second){

   int result = pow(first, second);

   return result;

}

int main()

{

   int side;

  cout<<"Enter the side of cube: ";

  cin>>side;

  int volume = to_the_power_of(side, 3);

  cout<<"The volume is "<<volume<<endl;

  return 0;

}

Explanation:

include the library iostream and math.h for using the input/output instruction and pow() function.

create the main function and declare the variable.

then, print the message for asking to enter the value from user.

the enter value is then store in the variable using cin instruction.

then, call the function with two parameters. program control move to the define function and  calculate the first parameter raised to the power of the second parameter.

then return the result to the main function and finally print the result.

Answer and Explanation:

The characteristics of input/output of PC/workstation can be described as:

Input/Ouput devices works as the interface between the user and the device. It provides us to give commands to our system and get the outputs as per the commands or instructions provided.

Input devices are those which allow us to give instructions or commands to our system like that of a keyboard in a PC, it allows us to write into our system and give commands to it to perform a particular task. these instructions are then converted into signals to be readable by the system(machine language). Another input device is mouse.

Output devices are those which provides us with the desired results converted in the form readable by us. Like monitor of our PC displays the desired results and same goes for printer it prints the results.

There are different input/output files for different operating systems as in 'C' there is a whole library for input/out commands.

Answer:

The correct answer is B. Unity of command principle refers to the idea that each employee should report to only one manager.

Explanation:

The Unity of Command Principle is one of the 14 administration principles imposed by Henry Fayol that determines that none of the employees of an organization should receive orders from more than one superior.

That is to say, the principle of the unity of command establishes that no employee should have more than one superior in order to avoid confusing situations and disorders that affect the productivity of the organization in question.

Answer: D. Local variables are recognized by the main program

Explanation: Local variables can be accessed in the function that they are defined within .If you require the variables which should be accessible by  every function in a particular program the they should be defined globally in the program . Therefore  local variables are recognized by the main program throughout.

Answer:

d. Local variables are recognized by the main program.

Explanation:

Local variables are recognized by the main program, is a true statement.

However, message body in reachable by the main program, two methods can have the same header, and formal and actual parameters may have the same names are NOT true statements.

Answer:

 The stored program concept is defined as, in the architecture of computer where computer acts as internal store instruction and it is important because has high flexibility and user does not required to execute the instruction again and again. It is basically works on the principle of Von neumann architecture, as in which the instruction and the data are both same logically and can be used to store in the memory.

Answer:

#include <iostream>

using namespace std;

int main()

{

   //initialization

  float x=0.0;

  float y;

  char operation;

  //print the message

   cout<<"Please enter the operation (Addition or Subtraction): ";

   cin>>operation;

   //loop for enter th operand again until enter 'q'

  while(operation != 'q'){

       //print the message for operand x

      cout<<"\nPlease enter the operand x: ";

      cin>>x;

       //print the message for operand y

      cout<<"\nPlease enter the operand y: ";

      cin>>y;

   //check for condition for '+' and if true then add the operands

      if(operation == '+'){

          x=x+y;

      }else if(operation == '-'){  //if user enter '-' then subtract the operands

          x=x-y;

      }

      //print the output

      cout<<"\nThe output is: "<<x<<endl;

      cout<<"\nPlease enter the operation (Addition or Subtraction): ";

      cin>>operation;

  }

  return 0;

}

Explanation:

Create the main function and define the variable x equals zero and declare the variables y and operation.

print the message for the user to enter the operation ('+' or '-') by using the instruction cout.

Store the value in the variable by using the instruction cin.

Then, take the loop to repeat the statement again and again until the condition is true.

print the message inside the loop for asking about the operands from the user.

then, use condition statement for checking the operation and if condition match, then execute the particular operation.

The above operation executes until the user enters not enter the character 'q'.

when the user enters the 'q', the loop terminates and print the output.

Answer: the correct answer is c. unifying type .

Explanation:

The unifying type is the type to which all operands in an expression are converted so that they are compatible with each other.

Answer:

False

Explanation:

When you apply subtraction (arithmetic operation) on Pointer variable ,then pointer variable is decremented by the (integer*sizeofmemory).

Example

            #include<stdio.h>

           //driver function

             int main()

          {

            float *ptr=(float *)100; //initializing  ptr as pointer type

            ptr=ptr-2; //subtracting pointer by 2(integer)

           printf("New Value of ptr is %u",ptr);

            return 0;

          }

Output

New Value of ptr is 92

Explanation of Code

ptr = ptr   - 2 * (sizeof(float))

   = 100  - 2 * (4) //float size is 4 bytes

   = 100  - 8

   = 92

Answer:

3

Explanation:

do-while is the loop statement used for executing the part of the code again and again until the condition not false.

when the condition is false, the program terminates the loop statement and starts executing the next of the do-while statement.

It has the special property, it executes the statement first and then checks the condition.

So, it executes the statement once if we provide the condition false.

Another side, the other loop statement like for loop, while loop they check the condition first and then start executing the statement if condition true.

In the question, the counter is 5 and myPar is 1

then the program executes the statement first.

so, myPar = 1+2=3

myPar assigns through the value 3. then counter increase by one.

the counter value becomes 2.

then check the condition 2 <= 1, condition false and program terminate.

Therefore, the answer is 3.
