C Program to calculate the cube of a given number

In this tutorial, we are going to learn to write a C program to calculate the cube of a given number. This program will be going to simply like a square program in c.

So before moving the writing program of the cube, let’s know about the cube.

What is the Cube of a number?

When a number is multiplied by itself three times, the result is known as the cube of that number. Cube is also denoted by a power of 3.

For example:

cube of 3 = 3^3 = 3*3*3 = 27

How our program will behave?

  • Our program will take one integer value as an input.
  • Then this number will multiply to itself three times by using multiplication(*) operator.
  • For example if we have to calculate cube of 3 then first time we will muliply 3 to itself i.e. 3. After first time multiplication result will be 9.
  • Again we will multiply 3 to the result which is 9. After second time multiplication output will be 9*3 = 27
  • 27 is the output after calculating the cube of 3.

Program to calculate cube of an integer using C language

#include <stdio.h>
int main() {
    float num,cube;
    printf("Enter a number to calculate cube: ");
    scanf("%f", &num);
    cube = num * num * num;
    printf("Cube of %.2f = %.2f",num, cube);
    return 0;


Enter a number to calculate cube: 5 
Cube of 5.00 = 125.00
