Output of this code snippet?

What is the output of the following code?

int x = 0;
int i;
for (i = 0; i < 4; i++) ;
x++;
if (x == 3)
cout << "*";
I believe it is just *, but can someone confirm?

You could try actually compiling it to see for yourself. =P

Actually, as it stands, there will be no output. If you click on the little "cog wheel" icon at the top right corner of the code below you can see for yourself!

#include <iostream>
using namespace std;

int main() {
cout << "begin main()\n";

int x = 0;
int i;
for (i = 0; i < 4; i++) ;
x++;
if (x == 3)
cout << "*";

cout << "end main()\n";
return 0;
}


You could even add a few more output lines to help you follow the program flow?
