C char Keyword
Definition and Usage
The char keyword is a data type that is used to store a single character.
A char value must be surrounded by single quotes, like 'A' or 'c'.
The signed and unsigned keywords treat the char as an integer type.
A signed char can represent values between -128 and 127.
An unsigned char can represent values between 0 and 255.

The unsigned keyword can allow a char to represent larger positive numbers by not representing negative numbers. This does not have an effect on how characters are stored and represented.
