COBOL(Common Business-Oriented Language)

COBOL was designed in industries such as finance and human resources for business computer programs. COBOL uses English syntax which make it easier for ordinary business users to understand computer programming languages.

COBOL is used to develop applications for businesses. We can say it is not a taught language because we don't learn it as teaching tool ,we use it in practical applications.

Explanation:

A  mouse cable connects to a USB port.

You are able to remove it from your computer if needed and put it into a different computer or device.

Answer:

False

Explanation:

Static arrays are stored on the stack , having fixed size and scope within functions.

Example-

               int arr[10];

Static arrays can't update the values given by the user at the time of execution, they are initialized with some default values.So,we can't create list of servers at the time of program execution.  

But we can create list of servers using Dynamic arrays, because size is not fixed as it stores in heap and update at the time of execution.  

Example-  

              int* arr = new int[10];

              delete[] arr;

Answer: B. You must type a username to continue.

Explanation: "you must type a username to continue" is the most suitable error message of all the options given because it is the appropriate way and user-friendly approach to the user for correcting the error as compared to other options which consist of inappropriate words ,slang language or lengthy message which is not easily understood by the user.

Answer:

The answer is x=10; y=15;

There is no change in the values of the variables x and y.

Explanation:

The integer variables x and y are initialized to 10 and 15 respectively as given.

x=10 ;

y=15 ;

The values of variables x and y are passed as parameters to another method, as shown.

mystery (x, y);

The mystery method given in the question is used to assign the same value to both the variables. The value of both the variables hold the value of x, i.e., both the variables hold the value of 10.

void Mystery ( int one , int two )  

{  

// temporary

int temp;  

// temp initialized to value of variable one which contains the value of variable x

// temp = x or temp = 10

temp = one;

// one is initialized to the value of itself or value of x

// one = x or one = 10

one = one ;

// temp is assigned value of variable x through variable one

// temp = 10

// y is also assigned value of temp variable

// y = 10

two = temp;  

}

As shown in the above steps, the mystery method is used to assign same values to variables one and two.

The values of original variables x and y are not affected since x and y are not utilized or called inside the mystery method.

This type of passing of parameters to a method can be described as passing a copy of the values of the parameters to the method.

Value of variable x is passed into variable one while value of variable y is passed into variable two.

Hence, values of variables one and two can be changed and modified without affecting the values of original variables x and y.

Answer: The MOVZX instruction can be used only with unsigned integers.

Explanation:

The MOVZX instruction allows to move a value from a smaller source to larger source ,by the method of padding it focuses on the most significant bits of the targets with zeroes . The destination for MOVZX should be a register only.  MOVZX cannot be used with any other type of integer such as signed integer etc except for that it can be used with unsigned integers only.

Answer:

char sure;

   cout << "Are you sure you want to quit? ";

   cin >> sure;

   while (sure != 'Y' && sure != 'N'){

       cout << "Are you sure you want to quit? ";

       cin >> sure;

   }

Explanation:

The loop is used in the programming for executing the part of code or statement again and again until the condition is not false.

do-while is the loop statement but it has a special property, it prints the statement first then checks the condition.

So, the loop executes the statement once, if the condition is false in the starting.

In the other loops, condition checks first and then execute the statement accordingly.

To change the do-while to while, we write the statement once outside of the loop in the starting then execute the loop and put the same statement inside the loop and it runs again until the condition true.

After the above change, while loop works the same as do-while.

Answer:

A. a double

Explanation:

The syntax of the function is:

type name( argument_1, argument_1,...... )

{  

    statement;

}

In the above syntax "type" define the return type of the function.

for example:

int count( int n);

so, it return the integer. Because the return type is 'int'.

In the question,

double compute speed(double distance);

Here, the return type is double. So, it return double.

Answer: For better code management and modularity

Explanation:

An application consist several lines of code so when we break an entire code into several small procedures it becomes easy to maintain and look for errors while debugging. This process also is part of good code writing and hence easy to manage our code during testing and debugging phases of application development.

A Web page represents content formatted in HyperText Markup Language ( HTML). Web Browsers like internet explorer,firefox or google chrome can interpret this content and display the page as specified in the markup. If we access any webpage on the browser and view its source we can see the HTML content underlying the webpage.

Answer:

The two main differences between arrays and structures are as following according to me :-

1. Array is collection of data elements of same data type while a structure is collection of variables of different data types.

2.Array is a primitive data type while structure is a user defined data type.

There are other differences also which are as following:-

1. The size of array is fixed while the size of structure is not fixed as structure can contain different variables of different data types.

2.array is declared as following :-

int array [100];

where 100 is the size of the array means it can store up to 100 integer values.

struct class{

int roll_number;

char *name;

int admission_no;

};

3.Traversing and searching in an array is easy and fast while it is difficult and slow in structures.

Answer:

In mathematics and digital electronics, a binary number is a number expressed in the base-2 numeral system or binary numeral system, which uses only two symbols: typically "0" and "1". The base-2 numeral system is a positional notation with a radix of 2. Each digit is referred to as a bit.

Answer:

The binary number system is an alternative to the decimal (10-base) number system that we use every day. Binary numbers are important because using them instead of the decimal system simplifies the design of computers and related technologies. ... But if the second digit is 1, then it represents the number 2.

Explanation:

Answer:

yes, it matter in what order the arguments  are passed.

Explanation:

when we define the function in the programming, you have to call the function as well.

In the calling function, we passed the arguments.

In the define function, parameters in declare for taking a copy of the arguments.

for example:

int print(int value, double price, char a){

    statement;

}

//calling

print(5, 7.8, 'a');

So, in the calling function the order of the argument changed, it gives the compile error.

because 5 is the integer, so you have to store in the int parameter.

print(7.8, 5, 'a'): if we try to do that, 7.8 which is double store in the wrong integer parameter, it gives the wrong output.

similarly, if we define the array in the parameter and pass the integer in the argument on the same location. it gives the compile error.

Therefore, the location must be the same.

Answer:

False

Explanation:

The order of arguments sent matters because what if you were trying to assign a int parameter as string, moreover there is one to one mapping and thus the results computed by the function will be wrong too. The order may cause a bug in the functionality (when the wrong value is assigned to the wrongly selected parameter due to alteration in order), cause run time errors ( when the data type of parameter and argument does not match due to alteration in order )

Answer:

Hi!

// First you have to initialize the variables.

int hits = 0;

int atbats = 0;

float percentaje = 0;

function eligible() {

    hits = inputHits(); //  Function that input the hits.

    atbats = inputAtBats(); //  Function that input the at bats.

    percentaje = hits/atbats; //  Now, you can calculate the percentaje.

    if( percentaje > 0.300) { //If percentaje if greater than .300 will print Eligible for the All Stars Game.

         print('Eligible for the All Stars Game.');

          } else { //Otherwise will print Not elegible.

             print('Not elegible.');

         }

     }

}

Explanation:

Answer:

has no body.

Explanation:

An abstract method is a method which has no body.

It is contained in a class which is marked as abstract.

The implementation of such method is specified in a subclass.

For example:

//abstract class

abstract class myClass{

  /* Abstract method */  

  public abstract void mymethod(int a, int b);

}

//Concrete class extending abstract class

class Concrete extends myClass{

  public void mymethod(int a, int b){

return a+b;

  }

}

Answer:

#include <stdio.h>

int main()

{

   int i, j, n, prime;

   printf("Enter till where we want to find prime number: ");

   scanf("%d", &n);

   for(i=2; i<=n; i++)

   {

       prime = 1;  

       for(j=2; j<=i/2; j++)

       {

           if(i%j==0)

           {

               prime = 0;

               break;

           }

       }

       if(prime==1)

       {

           printf("%d, ", i);

       }

   }

   return 0;

Explanation:

A number  which is divisible by 1 and itself is called prime number. Here in the program we start by taking number from 1 to n , where n is the last number till which we are required to find prime numbers. Then we start the loop by taking two for loops one for running the numbers from 1 to n and the inner for loop to check whether the number is divisible other than 1 and itself. We take the current number as prime =1. If the number is still not divisible by number other than 1 and itself we consider that number to be prime and print it.

Answer: Static local variable is a variable that is initialized as static only one time inside a function and whenever it is called in that function it will be accessible.

Explanation: Static local variables are very useful variables which are declared as static in a particular function. Static local variable is initialized only one time in a function and whenever the function in which it has been declared ,the value of the variable will be accessible by as many times it has been called in the function in which it is declared.

Answer:

a)13 bits

b)15 bits

Explanation:

a)

It takes 10 bits to address within a 1024-word page because 1024= 2^10.

Since the logical address space is 8 = 2^3 pages,

We will add 10 bits for 1024 words

10 + 3 = 13 bits must be the logical addresses.

b)

There are 32 = 2^5 physical pages.

We will add 10 bits for 1024 words

Similarly, physical addresses are 5 + 10 = 15 bits long .

Answer:

True: In half Duplex communication both of the hosts can transmit and receive. But can not do both job simultaneously.

when one host is sending other one can receive but can not transmit. And the receiving host waits for the transmitting host to finish transmitting, before it starts transmitting from it's end.

When one host is receiving other one can transmit.

For example- The communication system of army people. when one person talks the person in the other end has to wait till he finishes. They can not talk simultaneously.

Explanation:

Where in full duplex the both hosts can transmit and receive simultaneously, in half duplex system that's not possible.

Answer:

The length of the ladder should be 277.85 meters long

Explanation:

Great question, it is always good to ask away and get rid of any doubts that you may be having.

I have created an illustration and attached it as a photo below to better help you understand the situation. As seen on the illustration the difference in height of Building B from Building A is,

[tex]350m-210m = 140m[/tex]

Now that we have the difference we need to find the length of the ladder which is the hypotenuse between the two buildings. We can calculate this by using the Pythagorean theorem which is the following

[tex]h^{2} = a^{2} +b^{2}[/tex]

Now we can plug in the values and solve for the hypotenuse (h)

[tex]h^{2} = 240^{2} +140^{2}[/tex]

[tex]h^{2} = 57,600 +19,600[/tex]

[tex]h^{2} = 77,200[/tex] ... square root of 77,200

[tex]h = 277.85m[/tex] .... rounded up

Therefore, the length of the ladder should be 277.85 meters long

Answer:

The # marker is used to mark a line comment in python.

Explanation:

The line that starts with # is a comment.Python will ignore the lines that starts with #.These comments can be used to add extra information in the python code.

For example:-

Following is the python code with comments.

names=['sam','optimus','bumblebee'] #names is the list of transformers characters.

for i in names:

     print(i)  #printing the names.

There are 2 comments in the python code written above.These are ignored by python.

Answer: In operating system a code segment which accesses  some shared variables or resources one at a time atomically such other no other code or process is accessing that resource or variable at the same time.

Entry section code block allows the access to the shared resource or variable and exit section code signals the termination from access to the shared resource or variable.

Explanation:

Entry and exit section codes needs to check certain properties before allowing the access and removal of access to a particular code segment.

These conditions are:

1. Bounded waiting.

2. Mutual exclusion.

3. checking thread execution status to allows other threads to enter the critical section (CS).

Answer:

false

Explanation:

-exec option is not mandatory for the find command.

find will still list out the identified files even in the absence of -exec option.

For example:

find . -name test -print

will print out files with the name 'test' in the current directory. Note that there is no exec option in this example.

Same holds true for find with no additional options at all.

For example:

find .

will list out all files in the current directory.

Answer:

public class average{

   public static float getAverageOfFours(int[] arr){

       int n = arr.length;

       float sum = 0;

       int count=0;

       for(int i=0;i<n;i++){

           if(arr[i]%4==0){

               sum = sum+arr[i];

               count++;

           }

       }

       float avg = sum/count;

       return avg;

   }

    public static void main(String []args){

        int[] array = {10, 48, 16, 99, 84, 85};

        float result = getAverageOfFours(array);

        System.out.println("The average is "+result);

    }

}

Explanation:

Create the function with one parameter and return type is float.

Declare the variable and store the size of array. Take a for loop for traversing in the array and and check the element is divisible by 4 or not by using if statement. If condition true take the sum and increment the count.

This process continue until the condition is true.

finally take the average and return it.

Create the main function for calling the function with pass the array as argument and also define the array.

After that print the result return by the function.
