#include <stdio.h>int main(){ int num, cube; // Asking for Input printf("Enter an integer: "); scanf("%d", &num); cube = num * num * num; printf("Cube of %d is %d", num, cube); return 0;

This is a simple C program that calculates the cube of a given integer. Here's a step-by-step explanation:

1. #include <stdio.h>: This line includes the standard input/output library in C. This library allows the program to perform input and output operations.

2. int main(): This is the main function where the program execution begins.

3. int num, cube;: Here, two integer variables 'num' and 'cube' are declared.

4. printf("Enter an integer: ");: This line prints the message "Enter an integer: " on the console.

5. scanf("%d", &num);: This line takes an integer input from the user and stores it in the variable 'num'.

6. cube = num * num * num;: This line calculates the cube of the number entered by the user by multiplying the number by itself twice and stores the result in the variable 'cube'.

7. printf("Cube of %d is %d", num, cube);: This line prints the cube of the number on the console.

8. return 0;: This line signifies that the program has executed successfully and it returns 0 to the operating system.

9. The program is enclosed in {} brackets which define the body of the main function.
