How to make simple Calculator in C

C Arithmetic Calculator

While doing some mathematical problems, calculator plays a major role. We the programmer, are not supposed to use physical calculator, we just create it by our own coding. Here is a C program to perform arithmetic operations for solving your mathematical problems.

C Program - Arithmetic Calculator

It's time to write a c program to perform arithmetic operations.

C Program to Create Simple Calculator 

#include<stdio.h>

int main()

{

int n,a,b;

printf("1 for addition\n");

printf("2 for subtraction\n");

printf("3 for multiplication\n");

printf("4 for division\n");

printf("please enter 1-4 digit\n");

scanf("%d",&n);

printf("Please enter two numbers:");

scanf("%d %d",&a,&b);

switch(n)

{

case 1:

printf("%d",a+b);

break;

case 2:

printf("%d",a-b);

break;

case 3:

printf("%d",a*b);

break;

case 4:

printf("%d",a/b);

break;

default:

printf("you enter wrong key\n");

}

}
