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;

}

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.
