C 语言使用函数执行算术运算程序

编写一个 C 语言程序，使用函数执行算术运算，如加法、减法、乘法和除法。在此示例中，我们创建了多个函数，这些函数接受两个整数值并执行加法、减法、乘法、除法和取模运算。

#include <stdio.h>

int addition(int num1, int num2)
{
    int sum = num1 + num2;
    return sum;
}

int subtraction(int num1, int num2)
{
    return num1 - num2;
}

int multiplication(int num1, int num2)
{
    return num1 * num2;
}

float division(int num1, int num2)
{
    return num1 / num2;
}

int modulus(int num1, int num2)
{
    return num1 % num2;
}

int main()
{   
    int num1, num2;
    
    printf("Enter the First Number  = ");
    scanf("%d",&num1);

    printf("Enter the Second Number = ");
    scanf("%d",&num2);

    printf("Arithemetic Operations on Integer Values\n");

    printf("Addition       = %d\n", addition(num1, num2)); 
    printf("subtraction    = %d\n", subtraction(num1, num2));
    printf("multiplication = %d\n", multiplication(num1, num2));
    printf("division       = %.2f\n", division(num1, num2));
    printf("modulus        = %d\n", modulus(num1, num2));
}
