Hello, 

Yesterday I downloaded Cygwin 1.7.21-1, Java JDK 7u25, and Netbeans 7.3.1 onto my Toshiba which is running Windows 8. When I downloaded Cygwin I got the following resources: gcc, g++, gdb, and make. When I downloaded Netbeans I downloaded the biggest package, which included Java, C/C++, and a whole lot more. I ran the sample welcome program with no issue, but when I tried debugging the following programming: 

#include <cstdlib> 
#include <iostream> 
using namespace std; 

int main(int argc, char** argv) { 
std::cout << "Enter two numbers:" << std::endl; 
int v1 = 0, v2 = 0; 
std::cin >> v1 >>v2; 
std:cout << "The sum of" << v1 << "and" << v2 << "is" << v1 + v2 << std::endl; 
return 0; 
} 

I received this message:

BUILD FAILED (exit value 2, total time: 1s) 

Netbeans says there is no error in the code itself, and I tried looking up answers but all the solutions I found either didn't help or I didn't understand what it was saying. Can someone please tell me what the problem is here? 

Thanks!
