Question

how to to assign charather to perform additions (+), subtractions (-), multiplications (*), divisions (real always) n (/), and find the remainder (%) in c++

Expert Solution

Step 1

Program plan:

Include necessary header files.
Declare the “namespace”.
Define the “main()” function.
Declare and initialize the necessary variables.
The “do while” loop executes until the condition becomes false.
- Get the choice from the user.
- Define the “switch” case.
  - Case 1 for addition.
  - Case 2 subtraction.
  - Case 3 for multiplication.
  - Case 4 for division.
  - Case 5 for modulus.

Step 2

Program:

//Include the necessary header file

#include <iostream>

//Declare the namespace

using namespace std;

//Define the "main()" function

int main()

{

//Assign values to the characters

int a = 10, b = 2;

//Declare the variables

int c, choice;

char ans;

//Loop executes until the condition becomes false

{

//Print the statements

cout<<"1. Addition"<<endl;

cout<<"2. Subtraction"<<endl;

cout<<"3. Multiplication"<<endl;

cout<<"4. Division"<<endl;

cout<<"5. Modulus"<<endl;

//Print the statement

cout<<"Enter the choice: ";

//Get the choice from the user

cin>>choice;

//Switch case

switch(choice)

{

//Addition

case1:

c = a+b;

cout<<"The result of addition is: "<<c<<endl;

break;

//Subtraction

case2:

c = a-b;

cout<<"The result of subtraction is: "<<c<<endl;

break;

//Multiplication

case3:

c = a*b;

cout<<"The result of multiplication is: "<<c<<endl;

break;

//Division

case4:

c = a/b;

cout<<"The result of division is: "<<c<<endl;

break;

//Remainder

case5:

c = a%b;

cout<<"The result of modulus is: "<<c<<endl;

break;

//Default case

default:

cout<<"Enter the valid choice.";

}

//New line

cout<<endl;

//Print the statement

cout<< "Do you want to continue (Y/N)?"<<endl;

//Get the input from the user

cin >> ans;

} while((ans !='N')&&(ans !='n'));

}
