Develop a C program to perform addition, subtraction, multiplication, and division of two numbers using functions

Code
`#include <stdio.h>// functions declarationint add(int n1, int n2);int subtract(int n1, int n2);int multiply(int n1, int n2);int divide(int n1, int n2);// main functionint main(){    int num1, num2;    printf("Enter two numbers: ");    scanf("%d %d", &num1, &num2);    printf("%d + %d = %d\n", num1, num2, add(num1, num2));    printf("%d - %d = %d\n", num1, num2, subtract(num1, num2));    printf("%d * %d = %d\n", num1, num2, multiply(num1, num2));    printf("%d / %d = %d\n", num1, num2, divide(num1, num2));    return 0;}// function to add two integer numbersint add(int n1, int n2){    int result;    result = n1 + n2;    return result;}// function to subtract two integer numbersint subtract(int n1, int n2){    int result;    result = n1 - n2;    return result;}// function to multiply two integer numbersint multiply(int n1, int n2){    int result;    result = n1 * n2;    return result;}// function to divide two integer numbersint divide(int n1, int n2){    int result;    result = n1 / n2;    return result;}`
