C Arithmetic Calculator

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

Arithmetic Calculator Using C Programming

C Program - Arithmetic Calculator

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

#include <stdio.h>
int main()
int num1, num2, choice, answer;
printf("Enter any two integers : ");
scanf("%d %d ", &num1, &num2);
printf("\nPress 1 for Addition ");
printf("\nPress 2 for Subtraction ");
printf("\nPress 3 for Multiplication ");
printf("\nPress 4 for Division ");
printf("\nPress other key to exit ");
printf("\nEnter ur choice : ");
scanf("%d" ,&choice);
case 1:
answer = num1 + num2;
printf("\n%d + %d = %d ", num1, num2, answer);
case 2:
answer = num1 - num2;
printf("\n%d - %d = %d ", num1, num2, answer);
case 3:
answer = num1 * num2;
printf("\n%d * %d = %d ", num1, num2, answer);
case 4:
answer = num1 / num2;
printf("\n%d / %d = %d ", num1, num2, answer);
printf("\nInvalid Choice ");
return 0;
Enter any two integers : 20 10
Press 1 for Addition
Press 2 for Subtraction
Press 3 for Multiplication
Press 4 for Division
Press other key to exit

Enter your choice : 1
20 + 10 = 30
