Title: blocking off sections of code
Description: a little trick

Gday. If you are testing some code and want to block out a whole slab, then enable it again, then block it etc, you can employ this trick I thought of. (Maybe it's used all the time, but I haven't seen it anywhere)
Place //*/ at the end of the block you wish to hide. When you want to hide it,
simply place /* at the start of the block. It means you only have to worry about the starting comment.
Come to think of it... It's kind of like how they put some JavaScript in to hide it from old browsers.. Anyway, I hope someone finds this tip handy!
Nick.

EVERYONE knows that... You DIDN'T think of it... lol...
This forum has nice people that visit it! Sometimes programmers are not real nice... :)

yeah i have noticed that too i think ego has a big thing to do with it.... i think the reason we dont have it here so much is because everyone is learning and they talk how they want to be talked to. i have flamed a few people, but they deserved it ;)

The one problem with using comments to block of sections of code is that sometimes they don't work if the block has another embedded comment.
| CODE |
/* Comment out Block for debugging.
for(int loop=0;loop < max;loop++)
{
/*Print out the values in the array*/
std::cout << array[loop] << '\n';
}
*/
|
This is obviously a trivial example and can be made to work by changing the comment to C++ style comment. But commenting out large sections may require a lot of changes.
An alternative method is to use the pre-preocessor.
| CODE |
#if 0 // Commented out Block for debugging
for(int loop=0;loop < max;loop++)
{
/*Print out the values in the array*/
std::cout << array[loop] << '\n';
}
#endif
|
To turn it back on just replace the 0 with a 1.
