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.

## C programming code

int main()

{

int first, second, add, subtract, multiply;

float divide;

printf("Enter two integers\n");

scanf("%d%d", &first, &second);

add = first + second;

subtract = first - second;

multiply = first * second;

divide = first / (float)second; //typecasting

printf("Sum = %d\n", add);

printf("Difference = %d\n", subtract);

printf("Multiplication = %d\n", multiply);

printf("Division = %.2f\n", divide);

return 0;

}
