REALLY?! thats so weird.

lol

at least I can give myself credit for knowing how to read from an input file but WHY isnt it working on my computer?! I am 100% sure the input file makes sense.....

Well I know for a fact that it is not opening the txt file b/c I set numClasses to zero and the first integer in the input file is not zero, but the program still prints zero.

On any note, as i...

Well, this is very weird.
The input file contains two integers on the first two lines then some other data.....
It is called 'input' and it is a txt doc.
It is in the same folder as my program.

Pointer= An Address

Maybe, you can answer the question and be helpful... instead of getting smart.

Does this successfully allocate dynamic memory for the array?
