brrrrrr, thats not the best way for explaining , what do you want
tell then, which results you looking for,what do you need:
to know lenght of string, to do the massive of strings, or what?

to work on strings is enought to see theory about them :
1) string is a massive(note that!) of symbols(char) , with last element '\0'
2) there are some functions allows you to copy , unite , compare strings(leght and identity)...
