[SOLVED] can't run executable files

peter576 · 11-02-2011, 06:31 AM

Hello!
My problem is that I tried to compile a C++ file and it worked well, I compiled a HelloWorld.exe, HelloWorld.out, HelloWorld without extension and none of them can be executed, if I click on them nothing happens and I can't start them from terminal (maybe I should use a command to run them, I don't know)
And the code is:

#include <iostream>
using namespace std;

int main() {
cout << "Hello World \n";
cin.get();
cin.get();
return 0;
}

There was no error when compiling.
I'm using Ubuntu 11.10

Because your program is using terminal I/O, you need to run it from a terminal (otherwise it has nowhere to send the output, and will hang waiting for input).

To run it from the terminal, you should invoke it with a preceding './', ie:

Code:

./HelloWorld.out

You cannot invoke it using only the name (since the default path does not include the current directory; this is done deliberately to prevent the accidental running of malicious programs).
