What is the char value for?
The char data type is an integral type, meaning the underlying value is stored as an integer, and it’s guaranteed to be 1-byte in size. However, similar to how a boolean value is interpreted as true or false, a char value is interpreted as an ASCII character. … Character literals are always placed between single quotes.
