Contiguous  -  This means "touching". Two blocks of memory are contiguous if one begins immediately after the first one ends.
Null Character  -  This is the character that is used to mark the end of strings in C. It is written "\0" and has the ASCII value zero.
Null-Terminated  -  This means that the last element in an array is the null character. Strings in C are said to be null-terminated, and many string functions rely on this property.
Local  -  This refers to things that apply to the current function but do not apply outside the current function call. For example, a local variable is a variable declared inside a function that disappears when the function returns.
