Program to calculate basic arithmetic operations.

Using Visual Studio 2015

===============================================================

#include<iostream>
using namespace std;
#include<conio.h>
void main()
{
 

char O;

 float num1,num2,Multiplication,Addition,Subtraction,Division;
 

cout<<"enter First Number=";
 

cin>>num1;
 

cout<<"enter Second Number=";
 

cin>>num2;
 

cout<<"enter an operator=";
 

cin>>O;
 

switch (O)
 

{
 

 case '+':
  

Addition=a+b;
  

cout<<"\nAddition="<<Addition;
  

break;
 

 case '*':
   

Multiplication=a*b;
  

cout<<"\nMultiplication="<<Multiplication;
  

break;
  

case '/':
  

Division=a/b;
  

cout<<"\nDivision="<<Division;
  

break;
  

case '-':
  

Subtraction=a-b;
  

cout<<"\nSubtraction="<<Subtraction;
  

break;
  

default:
  

cout<<"\ninvalid input";
  

break;
 }
 _getche();
}

It is a program to calculate the basic arithmetic operations. In this case, 'Switch statement' is used.

The calculating operations are introduced in "char", because arithmetic operations are basically characters.
