### Calculate Cube of a Number in C, C++

Write a C, C++  program to calculate cube of a number. How to find the cube of a number using  C, C++ program .  It's a basic programming question in which a number is input by a user and our program calculate it's cube.

How to Calculate Cube of a Number

Suppose a user has entered 5.  Cube of 5 is : 5 * 5 * 5  (125) . Similarly, We can calculate cube of any number by multiplying the same number three times.

Find cube root of a number.

## C Program to Calculate Cube of a Number

```#include<stdio.h>

int main() {

int num,cube;

printf("Enter number \n");
scanf("%d",&num);

/* Cube is calculated. */

cube = num * num * num;

printf("Cube of a number is %d",cube);

return 0;
}

```

## C Program to Find Cube of a Number using Function

```#include<stdio.h>

int calculateCube(int num){

/* Cube is calculated and return. */

return num * num *num;

}

int main() {

int num,cube;

printf("Enter number \n");
scanf("%d",&num);

/* Cube function is called. */

cube = calculateCube(num);

printf("Cube of a number is %d",cube);

return 0;
}

```

## C++ Program to Calculate Cube of a Number

```#include<iostream.h>

using namespace std;

int main() {

int num, cube;

cout << "Enter number \n";
cin >> num;

/* Cube calculation. */

cube = num * num * num;

cout << "Cube of a number is" << cube;

return 0;

}

```
Output

Enter number : 5

Cube of a number is : 125

Explanation

In this program, We are taking a number as an input from a user then the cube of a number is calculated.

Basic programming questions for practice

1. Good you share this steps on how to find the cube of number by c++ programming language.

2. how to insert our program in any machine?please reply if any one knows.

3. Error --int main (( {
It should be int main()

4. program not applicable for n=100

1. Instead of int data type, You can use long int. As cube of 100 exceeded than int datatype limit.

5. its working. Thanks
