• C program to perform basic arithmetic operations which are addition, subtraction, multiplication, and division of two numbers.
• Numbers are assumed to be integers and will be entered by a user. In C language when we divide two integers we get an integer as a result, for example, 5/2 evaluates to 2. As a general rule integer/integer = integer and float/integer = float or integer/float = float.
• So we convert denominator to float in our program, you may also write float in the numerator. This explicit conversion is known as typecasting.

CODE

#include <stdio.h>

int main()
{
int first, second, add, subtract, multiply;
float divide;

printf("Enter two integers\n");
scanf("%d%d", &first, &second);

subtract = first - second;
multiply = first * second;
divide = first / (float)second;   //typecasting

printf("Difference = %d\n", subtract);
printf("Multiplication = %d\n", multiply);
printf("Division = %.2f\n", divide);

return 0;
}
