Program to make a simple calculator

Do you want to make a simple calculator in programming c. If yes then you are at the right place. In this article i will be publishing a simple code in programming c to make a simple calculator. This calculator will only  do some simple tasks like plus, minus, multiply and divide. So, lets get started.

CODE FOR CALCULATOR

#include<stdio.h>
#include<conio.h>
void main(){  

    int a,b;
    char c='+';
    printf("enter two no.'s with operator like a-b ");
    scanf("%d%c%d",&a,&c,&b);
   
    switch(c){
    case '+':
    printf("%d + %d = %d\n",a,b,a+b);
    break;
    case '-':
    printf("%d - %d = %d\n",a,b,a-b);
    break;
    case '*':
    printf("%d x %d = %d\n",a,b,a*b);
    break;
    case '/':
    printf("%d / %d = %d\n",a,b,a/b);
    break;
    default:
    printf("entered operator is wrong");
    break;
    }
getch();
}

INPUT/OUTPUT

In this program we don't have to put spaces or we don't have to click enter between no.'s and operator. So, If we input 55-13 the output will be 42.

Conclusion

We have to take two variables and one operator and then we have to use jumping statement switch case.
