Answer 1

Program in C++

#include<iostream>
using namespace std;
int cubeCalculator(int *Ptr )
{
*Ptr = *Ptr * *Ptr * *Ptr; // calculate cube of number
return *Ptr; // return cube
}

int main()
{
int number;
cout<<"Enter the number"<<endl;
cin>>number; // enter number
int cube=cubeCalculator( &number ); // call function by reference
   cout<<"Cube of number is : "<<cube;// print cube
return 0;

}

#include<iostream>
using namespace std;
int  cubeCalculator(int *Ptr )
{
   *Ptr = *Ptr * *Ptr * *Ptr; // calculate cube of number
    return *Ptr; // return cube
}

int main()
{
    int number;
    cout<<"Enter the number"<<endl;
    cin>>number; // enter number
    int cube=cubeCalculator( &number ); // call function by reference
        cout<<"Cube of number is : "<<cube;// print cube
    return 0;
