If string arrays are null terminated in C, why are arrays of other data types not null terminated?

Question

Strings, or arrays of characters in C must be null terminated to know where they end. Why does the same rule not apply to arrays of other types? eg. How does the computer kn

Answer 1

A string in C is a sequence of char that is null terminated. It's a special case of a char array.

You can have a char array that is not null terminated. For example:

char x[] = { 'a', 'b', 'c' };

Arrays in general are represented as a contiguous sequence of the base type in memory. The language itself doesn't keep track of how big an array is, you're expected to do that yourself.
