Thread: noob's question about the tutorial

why does this

Code:

#include <iostream>
using namespace std;
int main()
{
   int x;
  x = -9;
  do {for ( ;x < 10; x++ )
    cout<<"Count: "<<x<< " Hello, world!\n";
   }
   while ( x != 0 );
  cin.get();
}

print out a "count 0" line??!?

The same reason it runs "forever".

The `for' loop runs to completion every time the outer `do' loop iterates.

In other words, `x' never has the value zero in the outer `do' loop.

Ah! I see, it IS running forever... It seemed to have stopped at the 19th line and I assumed that it was done. I saw the count 0 line and improperly closed the window w/ the upper right "x" button. If I had bothered to hit hit enter I would have seen it was still running and given the code some more thought!! thank you!
