C program to calculate the sum and average of input two numbers using function

What is a function?

A function is a block of code that performs a specific task. Functions can be used to organize code and make it more reusable.

How to write a function in C?

To write a function in C, you need to use the following syntax:

return_type function_name (parameter1, parameter2, ...) { // Function body }

Example C program to calculate the sum and average of input two numbers using function

#include <stdio.h>

int sume(int, int); 

float average(int, int); 

int main()

{

    int num1, num2;

    int sum;

    float avg;

    printf("Enter the first number: ");

    scanf("%d", &num1);

    printf("Enter the second number: ");

    scanf("%d", &num2);

    sum = sume(num1, num2);

    avg = average(num1, num2);

    printf("First number: %d, Second number: %d\n", num1, num2);

    printf("Sum: %d, Average: %f\n", sum, avg);

    return 0;

}

int sume(int x, int y)

{

    int sum;

    sum = x + y;

    return sum;

}

float average(int x, int y)

{

      float average;

    return ((float)(x) + (float)(y)) / 2;

}

Output:

Conclusion:

We learned how to write a function in C and use it to calculate the sum and average of two numbers in this article. Functions are a powerful tool for organizing code and making it more reusable.
