What is meant by range in data type of c;like char has a range from 0 to 255?

Answer 1

Range means the maximum and minimum value that can be stored inside the variable of a given type. For example if you have unsigned char and if we assume that the size of the datatype is 8 bits then you can store values ranging from 0 - 2^8-1 i.e. 0-255 inside it.

Answer 2

we declare character like maybe a,b or any alphabet so is the value 0 to 255 has anything to do with ASCI values of alphabet.Can you please elaborate if yes or no.
