My awesome C++ triangle

//Homework 2, question 5

#include <iostream>
using namespace std;

int main(void)
{
 int n;
 int r, c;

 cout << "Enter a number: ";
 cin >> n;
 
 n = 2 * n + 2;
 
 for (r = 1; r <=n; r++, cout << endl)
     for (c = 1; c <=n; c++)
         cout << (r==1 || r==n || c==1 || c==n
              || r >= c || (r+c < n+1) ? ' ' : '*');

 return 0;  
}

You've never written a single line of code have you? Anyways, there is an error in that code that, no matter how shitty the compiler is, won't catch. The fact that you don't see it is okay. The fact that you keep arguing with me just implies you are some boneheaded fag that refuses to learn something.

Now shut up and tell me what the error is you mental midget you.
