Is there a reason why you have to use strcmp for C-style strings as opposed to ==?
Also, why isn't there a function/operator to compare arrays in the standard?
I'm sure there are good reasons why the language was designed this way, but just wondering why?

You can't overload operators for built in types. And because C-style strings are arrays, they decay to pointers when used in an expression. Thus, using == for both string comparison and pointer comparison would be ambiguous. You could come up with rules such as "== means string comparison with the arrays are of type char *", but that would hurt a lot of low level code that treats objects as strings of char. So the reason is that it would cause more trouble than it's worth.

There is, memcmp.

My best code is written with the delete key.
Thanks.
