Simple Calculator Program in C++ Language........................

Simple Calculator Program in C++ Language:

In this program, we are using only four basic mathematical operations like addition, subtraction, multiplication, and division. We perform these operations with the help of switch statement in C++. 

Program Code:

#include<iostream>

using namespace std;

int main()

{

int a, b, res;

char choice;

cout<<"1. Addition\n";

cout<<"2. Subtraction\n";

cout<<"3. Multiplication\n";

cout<<"4. Division\n";

cout<<"5. Exit\n";

cout<<"Enter your choice for Arithmetic operation : ";

cin>>ch;

cout<<endl;

switch(ch)

{

case '1' : cout<<"Enter two numbers a and b : ";

cin>>a>>b;

cout<<endl;

res=a+b;

cout<<"Result = "<<res;

break;

case '2' : cout<<"Enter two numbers a and b : ";

cin>>a>>b;

cout<<endl;

res=a-b;

cout<<"Result = "<<res;

break;

case '3' : cout<<"Enter two numbers a and b : ";

cin>>a>>b;

cout<<endl;

res=a*b;

cout<<"Result = "<<res;

break;

case '4' : cout<<"Enter two numbers a and b : ";

cin>>a>>b;

cout<<endl;

res=a/b;

cout<<"Result = "<<res;

break;

case '5' : exit(0);

break;

default : cout<<"Wrong Choice Entered........!!";

break;

}

cout<<"\n---------------------------------------------\n";

return 0;

}

The program output is tested on www.codechef.com

Output:

1.Addition 

2.Subtraction

3.Multiplication

4.Division

5.Exit

Enter your choice for Arithmetic operation : 1

Enter two numbers a and b : 2 3

Result = 5
