Write a program to enter a number and print its cube?

Answer 1

#include

using std::cin;
using std::cout;
using std::endl;

double cube(double number);//prototype

int main()
{
double number = 0.0;

cout << endl << "Enter a number: ";
cin >> number;

cout << endl << "Cube of " << number << " is " << cube(number) << endl;

system("PAUSE");
return 0;
}

double cube(double number)
{
return (number * number * number);

}

Also you can use the function pow(x, y) which returns x to the power of y (you have have include math.h).
