A constructor (check all that apply): Group of answer choices will always result in a run time error and program crash if it fails to test a parameter's value for validity before assigning the parameter's value to member. This will happen the first time we run a program, and alert us to the fact that there is a problem. must use mutators to initialize class data. must use assignment statements to initialize class data. may use assignment statements to initialize class data. may use mutators to initialize class data. will receive a compiler error if it fails to test a parameter's value for validity before assigning the parameter's value to member.

Answer:

Normal Margin is fit on the page. The default margins for Microsoft Word is normal margin.                                      

Explanation:

The paper visual effect give the document’s theme and quality. Margins send visual effects. Making a document right helps you to send the right message to readers. Use a small paper and adding a border.

You can change the page layout that people notice first with size, orientation, and margins.

Page margins make your document readable. Margins make the document more readable, make text look inviting, and given reviewers.

With narrower margins, you can reduce more words on-page.

To many words in a line make it difficult to read the document.

Margins are of many types

• Normal Margin
• Narrow margins
• Moderate margins
• Wide margins

Normal gives an equal inch to all sides of the page.

Narrow margins give little room to each column.

Average margins squeeze words from left and right.

Wide gives space when proofing the manuscript.

Answer:

A.) narrow margins

Answer:

System Interfaces.

Explanation:

Most new information systems must communicate with other, existing systems, so the design of the method and details of these communication links must be precisely defined. These are called system interfaces.

Answer:

Following are the program in the C++ Programming Language.

//header file

#include<iostream>

//header file

#include <bits/stdc++.h>

//namespace

using namespace std;

//set main function

int main()

{

//set float type variables

float a,s,m,d,c,b,g;

//print message and get variable from the user

cout<<" Enter The First Number : ";

cin>>c;

//print message and get variable from the user

cout<<" Enter The Second Number: ";

cin>>b;

again:

//get variable from the user for Operation

cout<<" Enter the Operation which you want : ";

char choice;

cin>>choice;

//Addition

a=c+b;

//Subtraction

s=c-b;

//Multiplication

m=c*b;

//Division

d=c/b;

//Modulus

g=fmod(c, b);

//set switch statement

//here is the solution

 switch(choice)

 {

   case '+':  

     cout<<"Addition: "<<a<<endl;

     goto again;

     break;

   case '-':

     cout<<"Subtraction: "<<s<<endl;

     goto again;

     break;

   case '*':

     cout<<"Multiplication: "<<m<<endl;

     goto again;

     break;

   case '/':

     cout<<"Division: "<<d<<endl;

     goto again;

     break;

   case '%':

     cout<<"Modulus: "<<g<<endl;

     goto again;

     break;

   default:

     cout<<"Exit";

     break;

 }

return 0;

}Explanation:

Here, we define the required header files then, we set main function.

• set float type variables a,s,m,d,c,b,g.
• Get input from the user for operation in the variable c,d.
• Set character type variables in which we get input from the user for operations.
• Then, we perform some operations.
• Set switch statement which display the output according to the user an if user input wrong then statement breaks.

Answer:

Editor. An editor is the individual in charge of a single publication. It is their responsibility to make sure that the publication performs to the best of its ability and in the context of competition. A managing editor performs a similar role, but with greater responsibility for the business of the publication.
