C in 100 Seconds: strlen strcpy strcmp — Strings in C | Episode 11

C doesn't have a string type. A string is just a char array with a null terminator at the end. Double quotes create one automatically — C adds the backslash zero for you. strlen counts characters before the terminator. strcpy copies one string into another buffer — you can't use equals. strcmp compares two strings — zero means equal, negative means the first comes first alphabetically.
