macOS Comparing characters in a string?

[Simplicated]

Hello, I have two strings here

ABCDEFGH

and another one

AACCEEGG

I want to compare them, one character at a time.

Is there any ways to achieve this in Obj-C?

Thank you very much.

Sure, have a look at NSString's characterAtIndex: method, all you need is an int to keep track of the index as you walk down the string (check the length of both strings first if you can't be sure they'll be the same). If you have C strings instead of Unicode NSStrings, you can easily do it using C pointers and directly comparing the value of each character value.
