C99 boolean data type lists the name, size, and range of the boolean data type. The compiler recognizes this data type when compiling C99 (ISO/IEC 9899-1999) source code.
| This type | has this size | and holds this range of values |
|---|---|---|
| _Bool | 8 bits when pragma uchar_bool is on , 32 bits when pragma uchar_bool is off | 0 ("false") and 1 ("true") |
