char C Keyword char char is a C data type. It is the smallest addressable unit of data. According to the ANSI Standard, a char consists of exactly one byte of storage; a byte, in turn, must be composed of at least eight bits. sizeof(char) returns one by definition, with all other data types defined as multiples thereof. All Mark Williams compilers sign-extend char when it is cast to a larger data type. Under COHERENT, a char by default is signed. ***** See Also ***** byte, C keywords, data formats, unsigned COHERENT Lexicon Page 1
