ith reference to McCall's quality modle , what are the three important aspects of a software product ?

Answer:

A,B,C -NO

D-Value type like int,char..

E.pop

D. it throws null exception

Explanation:

(A,B,C)There is no functional difference but  as the values passed to the parameterized constructor is different so you will get different outputs but functionality of the class didn't change  

(D) stack is a data structure which stores value types where as heap stores object types.In.stack actual value of the variable stored and heap address of the object stored

(E)the top operation on stack is always pop once we inserted the elements in a stack.if there are no elements in stack pop results null

(D) if the string we passed is null or empty to the test method it returns exception we need to handle that

Answer:

Transmission Control Protocol

Explanation:

Transmission Control Protocol is using connectionless services if network layer is providing connection oriented services.

Answer:

The answer is true.

Explanation:

An array is a collection of data of the same type. It is used to handle a number ''n'' of elements in common, either of types defined by the language ( int, float, string, etc) as well as those defined by the programmer.

A one dimensional array is a structured data type that is made up of a finite, ordered collection of data of the same type.

A vector, also called a one dimensional array, is a data structure that allows you to group elements of the same type and store them in a single block of memory together, one after the other. This group of elements is identified by the same name and the position in which they are found. Ther first position of the array is position zero.

We could group in an array a series of elements of integer type, floating, etc. For example:

int a [5]; (vector of 5 integers)

float b[5]; (vector of 5 floating)

int a [] = {5,6,7,8,9};

float b [] = {5.1,5.2,5.3,5.4,5.5};

Since there are 5 elements in each array, automatically 5 memory spaces will be assigned to each vector, but if I try to create the vector of the form int a [], the compiler will show an error, because I did not indicate the size of the vector and I did not initialize its elements.

Answer: The major responsibility of a programmer is the development of the computer programs for an organization.

Explanation: Programmers tends to have good programming language knowledge for developing programs according to the need. They are supposed to create coding pieces as per the requirement in a software programming language. They are also have a duty of testing the program code. They should persist the skill of problem solving as well as critical thinking to be a good programmer in a particular organization.

Answer:

Procedure are used to create and modifying the programs. Basically, it is grouping of instruction that can be used give direction of the flow of program. Control are given to the next term once the execution of the instruction get over. The steps of procedure are:

procedure are first executed the declaration instruction and then coding the procedure, then it will return to the directories and the last executable instruction is the termination of procedure.

Answer: (B) &x

Explanation:

Here whenever any variable is stored let it be integer, char, float it is always stored in a memory location assigned as '&'. Here the location where x is stored is denoted as '&x' which means memory address of x. *x means the pointer which is pointing to the memory address of x.

Answer:

true

Explanation:

The command:

find -empty -type f -exec rm { } \;

carries out the following steps.

1) Finds all the empty files in the current directory and its subdirectories.

2) For each of the identified files, it executes the command specified as the parameter to exec option,namely, rm <filename>.

So effectively it removes all empty files in the directory tree starting at the current directory.  

Answer:

WCF -  Windows Communication   Foundation

Explanation:

WCF stands for Windows Communication   Foundation.

The first version of WCF is released as   a part of .NET 3.0.The later versions are 4.0 and   4.5.

WCF is used to build distributed applications.   Distributed application is an application that where   parts of it run on two or more systems.  

For example,  

We have a web application running on one server. If   this web application is consuming a web server   which is running on another server, then this  

application is called distributed application.

The programmers can also build 3-tier web   application. The 3-tiers are,

          1. Presentation tier

          2. Business tier

          3. Data Access tier

If all 3 tiers are deployed on same machine,   scalability can be an issue, if more number of users   try to access the application.  

If we deploy each tier on different machines, then it   can handle multiple requests without degrading   performance of an application.

WCF is also used to build interoperable applications.  An interoperable application is an application where   one application can communicate with any other   application that is built on any platform.

So, the two advantages of using WCF are:

provided by other.  

Earlier, we used to have web services and .NET   Remoting to build distributed applications.  

Microsoft unified these communicating technologies   and named it as WCF.

Answer:

ampersands

Explanation:

In the programming the AND operator is denoted as '&&' , two ampersands.

it is used to between two conditions and give Boolean result.

It has four possible result:

first condition TRUE  second TRUE, result TRUE

first condition TRUE  second FALSE, result FALSE

first condition FALSE second TRUE, result FALSE

first condition FALSE second FALSE , result FALSE

For example:

(5 > 0 && 7 > 4):   it gives the result TRUE because both are true.

5 > 8 && 7 > 4):   it gives the result FALSE because one is false.

Answer:

Option A is the right answer. When designing a database the first step is to clearly define the purpose of database. What are the primary goals you want to achieve by building a database for a specific purpose. There are various methods of defining core purpose of database design.

Explanation:

Answer details  

Grade: College

Subject: Computers and Technology

Chapter: Database Design

Keywords: designing database, relations in database, primary key etc

Final answer:

The correct answer is "clearly define the purpose of the database". The first step in designing a database is to clearly define its purpose, which guides all other design decisions such as table organization, relationships, and primary keys.

Explanation:

When designing a database, the first step should always be to clearly define the purpose of the database. This involves understanding its main functions, the kind of data it will contain, and how that data will be used. It's essential to document the purpose of the database, its anticipated users, and the ways in which it is expected to be utilized. This foundational step is critical for guiding subsequent design decisions, such as data modeling, establishing table relationships, and choosing primary keys.

After the purpose is defined, the next steps involve organizing the data efficiently. This includes dividing data into tables to minimize redundancy and establishing table relationships to link related data effectively. Defining primary keys for each table is another crucial step to ensure that each record can be uniquely identified, thus maintaining data integrity and facilitating data retrieval.

Answer:

B) Throwable

Explanation:

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

There are a wide range of classes on the exception class hierarchy. All the way on the top is the Objects Class but since that is not an available answer we will move on to the next one. The next one is the Throwable class. therefore that is the answer.

**Exception is after Throwable , and Arithmetic Exception is at the bottom.... everything is a class so that is not a part of the hierarchy **

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

The answer is action eventlistener

Explanation:

It is an event handler and it is easy to implement.In java we call them even listeners it is function or a sub routine or a procedure that waits for an event to occur and respond to an event from a GUI component.

Answer:

 #include <iostream>

using namespace std;

int main()

{

  float radius = 5.4;

  float circumference = 2 * 3.14 * radius;

  float area = 3.14 * radius * radius;

  cout<<"the circumference of the circle is "<<circumference<<endl;

  cout<<"the area of the circle is "<<area<<endl;

  return 0;

}

Explanation:

Include the library iostream for using the input/output instructions.

create the main function and define the variable with value. Then,

use the formula to calculate the circumference and are of circle.

[tex]circumference = 2*\pi *radius[/tex]

[tex]area = \pi * radius^{2}[/tex]

here, choose [tex]\pi = 3.14[/tex]

after that, display the result.

Note: All variable define in float type.

Answer:

#include<stdio.h>

//main function

int main(){

   //initialization of variable

   char arr1[12][12] = {"January","February","March","April","May","June","July","August","September","October","November","December"};

   int arr2[12]={31,28,31,30,31,30,31,31,30,31,30,31};

   int i,j;

   //for loop for print the arrays

   for(i=0;i<12;i++){

     for(j=0;arr1[i][j]!='\0';j++){

       printf("%c",arr1[i][j]);    //for print the months

     }

     printf(" %d",arr2[i]);   //print the days

     printf("\n");  //for newline

   }

   return 0;

}

Explanation:

Create the main function and then define the two array with hard-code the month names and number of days in each month.

For defining the string array, you have to take the 2-D array of type 'char'.

then, take nested for loop for print the element in the array.

nested for loop means, loop inside a loop. It is used for the 2-D array. The outer loop is for row and the inner loop is for the column.

For every row, the inside loop print the string character by character with the help of printf() function which is used to display the value on the screen.

after the inner loop terminates, then another prinf() function is used for print the days after the name of the month. Then. the outer loop runs again.

This is process continues until the outer loop not terminate and finally, we get the desired output.

Answer:

void printLarger (int num_1, int num_2){

   //if else statement for checking the condition

   if(num_1 > num_2){

       cout<<num_1<<endl;  //display the output

   }else if(num_1 < num_2){

       cout<<num_2<<endl;  //display the output

   }

}

Explanation:

Create the function with return type void, it means the function returns nothing.

The number will be large if it less than the second number.

The possible condition are:

1. number_1 > number_2: the number_1 will be large.

2. number_1 > number_2: the number_2 will be large.

In the programming, if-else is the conditional statement which is used for checking the condition and gives the output accordingly.

Syntax:

if(condition){

  statement;

} else if(condition){

   statement;

}

when the program executes the if statement checks if condition number_1 > number_2 is true or not if true then print the output.

if the condition false, then the program control move to the else if part and then checks the condition if the condition true then print the output.

Explanation:BECAUSE

Relational operators, specifically < and >, are used to create validation rules that data must satisfy when being entered or modified. They set conditions such as requiring a quantity to be at least one, as in >=1.

The operator used to create a validation rule is C. < or > which are relational operators. These operators are essential in forming expressions that set the conditions data must meet to be considered valid. For instance, a typical validation rule in an Order Entry form might be that the quantity entered must be equal to or greater than one. In this case, the rule would be represented as >=1.

In database systems and programming, the proper use of relational operators, such as <, >, <=, and >=, is critical for ensuring accurate querying and data integrity. These operators allow for comparison between values, ensuring that the entered data fits within the specified parameters defined by the validation rules.

Answer: Central

Explanation: Dimensional model is the model that is created for the requirement of analysis of a particular business such as data warehouse. It is usually referred as the fact table as well.  Dimensional model has one major table known as central table and multi-part tables connected with it.The combination of the smaller tables are known as the dimension tables also.

Answer:

15

Explanation:

The if else state is used for checking the condition and if the condition is TRUE and program can execute the statement  within the if else.

Initially input_value is 5

then the if statement check the condition 5>5, condition FALSE because 5==5

it not less than 5.

then program move to else if and check condition 5>2, condition TRUE.

then, input_value = 5 + 10=15 execute and update the value to 15.

After that, program terminate the if else statement.

Therefore, the answer is 15.

Answer:

import java.util.Arrays;

public class sort{

    public static void main(String []args){

       int[] arr = {2,6,9,1,5,3};

       int n = arr.length;

       Arrays.sort(arr);

       for(int i=0;i<n;i++){

          System.out.println(arr[i]);

       }    

    }

}

Explanation:

first import the library Arrays for using inbuilt functions.

create the main function and define the array with elements.

then, use the inbuilt sort function in java which sort the array in ascending order.

syntax:

Arrays.sort(array_name);

then, use for loop for printing the each sorting element on the screen.

Answer:

 #include<iostream>

using namespace std;

int main(){

   int number;

   cout<<"Enter the five-digit number: ";

   cin>>number;

   int result = 0;

   while(number != 0){

       int remainder = number % 10;

       result = result*10 + remainder;

       number = number/10;

   }

   cout<<"The reverse Number is: "<<result<<endl;

   return 0;

}

Explanation:

first, include the library iostream for using the input/output.

Then, create the main function and declare the variables.

Print the message on the screen by using the instruction cout.

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

Take the while which runs until the number not equal to zero.

In the while, first, take the remainder of the number by using the operator '%'.

for example:

number = 123 % 10, it gives the value 3 which is the remainder.

after that, we write logic to reverse the number:

initially, remainder =3 and result=0

result = result * 10 + remainder

so, the result will be 3

after that, suppose remainder =2 and result=3 (previous calculated)

result = 3* 10 +2.

so, the result will be 32. so the number is reversed. we store the number in reverse order.

This process continues until the condition is true.

After that, print the output.
