Oh ok, what about assigning NULL to iNumber and iGuess?

And then Its an endless loop because of (;;) ?

NULL = nothing. Instead of assigning it something else.

And it is and endless loop, but I perfer to use

Code:

While (1==1){}

Depending on your code, if you do not define variables with a value, you will run into errors. NULL is just the standard value to give anything you are creating at first, which means nothing, empty, etc. And yes, for (; means an endless loop unless you do something inside of the loop itself to exit it. _________________ - Retired.

NULL is just a #define for 0.

Bad coding practice, it adds an extra cmp instruction into the loop when it isn't needed.

Anyways, here is what you are looking for in proper C++, with error checking.

Fails:

Code:

Guess the number between 1-100. Begin...
Guess 1: Invalid input.

CTRL-C fails :<

Cheater. :<

And I'd prefer

Code:

::srand( ::time(NULL) );

As I previously told Nos3001, windows.h is a far more common header, so it is generally in your best interest to include that instead of ctime. It's all just personal preference though.

Really? So what would be the best infinite loop to use?
