Hello all,
My objective is simple. I have to take in 2 positive integers and multiply them by using addition. This is a recursive problem.
Example of Output:
Please enter 2 positive integers to multiply:
4 2
4 * 2 = 8
The problem is whenever the user types in both numbers, the program window just disappears.
To receive my result, I am suppose to use something like:
x + multiply(x,--y);
Please help me with this...Thank you
#include <iostream>
using namespace std;
int multiply(int x, int y);
int main()
{
int x;
int y;
cout<<"Please enter 2 positive integers to multiply"<<endl;
cin>>x;
cin>>y;
cout<<x<<" * "<<y<<" = "<<multiply(x,--y)<<endl;
system ("PAUSE");
return 0;
}
int multiply(int x, int y)
{
if (x == 0)
{
return 0;
}
if (x == 1)
{
return x;
}
if (x > 1)
{
return (x + multiply(x,--y));
}
}
