Program to find Addition, Subtract, Multiplication, Division and Remainder of 2 numbers in C

Program:

#include<stdio.h>

int main()

{

int num1, num2, sum, sub, mult, remainder;
float div;

printf("Enter 1st number: ");

scanf("%d",&num1);

printf("Enter 2nd number: ");

scanf("%d",&num2);

sum=num1+num2;

printf("Sum is: %d",sum);

sub=num1-num2;

printf("Subtraction is: %d",sub);

mult=num1*num2;

printf("Multiplication is: %d",mult);

div=(float)num1/num2;

printf("Division is: %f",div);

remainder=num1%num2;

printf("Remainder is: %d",remainder);
return 0;

}

Output:

Note:
We have used float for division since if we use div variable of int type answer we will get will be of int type.
e.g: If we use div variable of int type then 25/3 will give answer as 8 and not 8.333333

Summary:

+ is used for addition.
- is used for subtraction.
* is used for multiplication.
/ is used for division.
% is used to find remainder.
