Simple C++ Question
Feb 28, 2013 at 12:14pm
I need help understanding something simple.
How many times does the following loop execute, and what is its output ?
count = 1;
while ( count<= 12)
{
cout << count << endl;
cout++;
}
If someone could explain this I would greatly appreciate it. Thank you !

http://www.cplusplus.com/reference/ostream/ostream/
ostream has no operator++ defined.
Surely OP meant to write
Would this make more sense, OP:
The loop is going from count = 1 through 12. Or 1 to 13. Either way you word, it will fail on count = 13.
Count
1
2

7
8
9
10
11
12 <-- Last output.
13 <-- Fails here. Exits loop.

@ResidentBiscuit what would operator+ have to do with the post increment operator?
