how to count double characters ?

[Paul McKenzie]

lol i was waiting e replay " We wont do your homework for you " BTW .
Can you help me only with this part : I have this code which find a letter a and A . Now how to write like this but to detect the double letters :

Put away the programming for now.

Write down exactly the steps, even if it's in English, to traverse a string, searching for double letters. Otherwise, you're trying to conjure up magic by writing code, and programming doesn't work that way. Always plan what you're going to do before writing a single line of code.

You encounter a letter, is it a double, yes, no, etc. That is what you're supposed to plan out on paper before you write any function.
