| Doesn't C++ have a 'substr' function, much like PHP? I would use that, and don't forget to check if the string is empty. You'll be looking at an exception otherwise.

uhm..
you wont be deleting the last character of the arraywith that but making it null
and strlen doesnt read null characters, sizeof does
I think what you want is to use sizeof and then malloc to resize the array

I was assuming he was talking about a character array.
EDIT: Ah never mind, I said string instead of char, my bad.

What would the difference be between a string and a char array?

String is like a sentence (Like "Fuck you")
Char array is a series of characters (Like "F", "u", "c", "k", " ", "y", "o", "u")
Char array = wastes less memory
String = more memory

yeah I know what a string is I was just wondering since "char"(characters obv.), characters would be what a string consisted of; letters, symbols, numbers.
I was just wondering why there was a difference like that.

A char can be anything, a symbol/letter/etc... The only real reason I see it's good for is saving very small amount of data (Like saving an item on a game, and the item has a number id which is converted to a char), or memory management.

If it's just a number ID why not just store it as an integer variable?

Memory management. char = 1 byte, int = 4 bytes (or something like that)
