C++ Code Review: Basic Mathematics operations on two integer expression

Description: This program shows how to do basic mathematic operations on given two numbers. The specialty of the program is it takes expression as user input that means user has to enter the inputs along with operation symbol. Such as: 3+5, 6*7, 9/3, 25%4.

Code:

//Compiling Tool: Code::Block IDE with MinGW

//Program uses basic maths operators to do sum calculations.

 

#include<iostream>

#include<conio.h> //for getch()

#include<math.h>  //for sqrt()

#include<cstdlib> //for system()

 

using namespace std;

int main()

{

 

    system("cls");//to clear the screen

    int a,b, result;

    char c;

    cout<<"Enter two variables expression using +/-/*///% operator(Ex:25%4):";

    cin>>a>>c>>b;

 

    switch(c)

    {

    case'+':

        result = a+b;

        break;

 

    case'-':

        result = a-b;

        break;

 

    case'*':

        result = a*b;

        break;

 

    case'/':

        result = a/b;

        break;

 

    case'%':

        result = a%b;

        break;

    }

    cout<<"Result:"<< result;

    getch();

    return(0);

}
