Program Code – Sample Program in C Language

#include <stdio.h>

// Function to add two numbers
int addNumbers(int a, int b) {
    return a + b;
}

// Function to multiply two numbers
int multiplyNumbers(int a, int b) {
    return a * b;
}

int main() {
    int num1, num2, sum, product;
    
    // Taking input from the user
    printf('Enter two numbers: ');
    scanf('%d %d', &num1, &num2);
    
    // Calling addNumbers function
    sum = addNumbers(num1, num2);
    
    // Calling multiplyNumbers function
    product = multiplyNumbers(num1, num2);
    
    // Displaying the results
    printf('Sum = %d
', sum);
    printf('Product = %d
', product);
    
    return 0;
}

### Code Output:

Enter two numbers: 5 7
Sum = 12
Product = 35

### Code Explanation:

This C program demonstrates the use of functions and basic I/O (Input/Output) operations, tackling two fundamental operations: addition and multiplication. The program is structured into two custom functions, addNumbers and multiplyNumbers, alongside the main function, which is the entry point of any C program.

1. Function Definitions: The addNumbers function takes two integers as inputs and returns their sum. Similarly, the multiplyNumbers function also takes two integers but returns their product. These functions embody the principle of code reuse, making the program more modular and manageable.
2. User Input: In the main function, we start by declaring four integer variables: num1, num2, sum, and product. We prompt the user to enter two numbers by displaying a message using printf and then capture the user input through scanf. This demonstrates basic user interaction in a C program.
3. Function Calls: Once we have the input, we call addNumbers and multiplyNumbers with num1 and num2 as arguments. The returned values from these functions are then stored in the sum and product variables, respectively.
4. Displaying Results: Finally, we display the results (the sum and product of the input numbers) using printf. This utilizes formatted strings, a powerful feature of C for mixing text with variable values.

This program exemplifies the concept of breaking down a problem into smaller, more manageable sub-problems, each solvable by a specific function. It leverages basic C syntax and conventions, including function definition and calling, variable declaration, and user interaction through the standard input and output. It’s a simple yet effective demonstration of programming fundamentals in the C language.
