What does that mean--> char[100]? Does it mean that I can only write up to 100 characters in the input?

Answer 1

Char variable[100];

This means that you have a array of char if 100 positions (0 to 99). But you only can store a word with 99 letters because strings(array of char) will store '\0' character in last position to mark the end of your string.

Yeah by definition strings are a set of characters with \0 in end.
