cout doesn't print anything sometimes in Netbeans

Question

I'm programming in C++ with Netbeans 8.2 at school, these computers have Ubuntu 14.04 and gcc-4.3 .

The cout randomly works altought it doesn't send any errors in the log.

Every computer here has the same problem.

main.cpp:

#include <cstdlib>
#include <iostream>

using namespace std;

int main(int argc, char** argv) {

    cout << "Hello World!" << endl;
    return 0;
}

Posible (and expected) output:

Hello World!

RUN FINISHED; exit value 0,; real time: 0ms; user: 0ms; system: 0ms

Other posible output:

RUN FINISHED; exit value 0,; real time: 0ms; user: 0ms; system: 0ms

Answer 1

Sometimes the compiler prints out and finish without being noticed. So you can use cin to check if that is happening to you.

#include <cstdlib>
#include <iostream>

using namespace std;

int main(int argc, char** argv) {

    cout << "Hello World!" << endl;
    int test;
    cin >> test;
    return 0;
}

Here the compiler will wait for you to enter a value, so you will have plenty of time to see your output.
