An array of char is an string, but its methods are relative to arrays or the elements of the array. So for example if you want to look for the position of a carácter in an string of a class String then you use a method called IndexOf.
What is character set in C?
In the C programming language, the character set refers to a set of all the valid characters that we can use in the source program for forming words, expressions, and numbers. The source character set contains all the characters that we want to use for the source program text.
