Character Data Types - char

char is a special integer type designed for storing single characters. The integer value of a char corresponds to an ASCII character. E.g., a value of 65 corresponds to the letter A, 66 corresponds to B, 67 to C, and so on.

As in the table below, unsigned char permits values from 0 to 255, and signed char permits values from -127 (or -128) to 127. The char type is signed by default on some computers, but unsigned on others the sizes of the char types are as follows.

Type Bytes Minimal range

char 1 -127 to 127

unsigned char 1 0 to 255

signed char 1 -127 to 127
