C Program to print cube of a number upto an integer

In this article, we will write a C Program to print cube of a number upto an integer. For example, if the user enters a number 2 then program should print the cube of each number from 1 till the entered number. The output should look like this:

Enter an integer: 2
Cube of 1 is 1
Cube of 2 is 8

C Program to display cube of a number upto a given integer

The explanation of the program is provided at the end of this code.

#include <stdio.h>

int main() {
    //n: is the number till which the cube of every number is printed
    //i: is the loop counter variable
    int n, i;

    // Prompt the user to enter an integer
    printf("Enter an integer: ");
    scanf("%d", &n);

    // Loop to calculate and print cube of every number from 1 to n
    for(i = 1; i <= n; i++) {
        printf("Cube of %d is %d\n", i, i * i * i);
    }

    return 0;
}

Output:

Enter an integer: 7
Cube of 1 is 1
Cube of 2 is 8
Cube of 3 is 27
Cube of 4 is 64
Cube of 5 is 125
Cube of 6 is 216
Cube of 7 is 343

Explanation of the program:

1. C header files: In this program, we have included only one header file <stdio.h>, which is required for using the printf and scanf functions.
2. Main Function: The main functions contains the following statements.
   • Variable Declaration: Here, we have two variables, n and i. The variable n is to hold the user entered number and i is the loop counter variable.
   • User Input: The program prompts the user to enter an integer using printf. The scanf function reads the input and stores it in the variable n.
   • Loop to Calculate Cubes: A for loop iterates from 1 to n. Inside the loop, the cube of the current number i is calculated as i * i * i and printed using printf.
   • Return Statement: The return 0 statement represents the successful execution of the program.
