unsigned char

An unsigned version of the char data type. An unsigned char occupies 1 byte of memory; it stores an integer from 0 to 255.

Like an unsigned int, an unsigned char won’t store negative numbers; it is also subject to the same overflow issues as any integral data type.

Example

unsigned char c = 240;
