Recursive Multiplication C++

Recursive Multiplication
Write a recursive funct ion that accepts two arguments into the parameters x and y.
The function should return the value of x times y. Remember, multiplication can be
performed as repea ted addition:
7 * 4 = 4 + 4 + 4 + 4 + 4 + 4 + 4

Answer:

//  Recursive Multiplication
#include <iostream>
using namespace std;

// Function prototype
long multiply(int, int);

int main()
{
	// Let's multiply 7 by 4...
	cout << multiply(7, 4);
	cout << endl;

	return 0;
}

//*******************************************
// Function multiply                        *
// This function uses recursion to multiply *
// x by y. The multiplication is performed  *
// as repetitive addition.                  *
//*******************************************

long multiply(int x, int y)
{
	if (x == 1)
		return y;
	else
		return y + multiply(x - 1, y);
