Cube of given number

Description:

Assume that the program has functions, one to calculate the cube of given integer and another to find the cube of given float number Test Case 1 Input (stdin) 2 3.5 Expected Output Cube is 8 Cube is 42.875 Test Case 2 Input (stdin) -2 3.5 Expected Output Cube is -8 Cube is 42.875

Program :

#include <iostream>

using namespace std;

int main()

{

  int a,b;

  cin>>a;

  b=a*a*a;

  cout<<"Cube is "<<b<<"\n";

  float c,d;

  cin>>c;

  d=c*c*c;

  cout<<"Cube is "<<d;

return 0;
