C Language implementation BOOL type

BOOL evaluates to FALSE and true, which is the difference between 0 and 1, and false can represent 0, but true has many kinds. Not only 1. BOOL is a type of definition in C + +, how do we implement bool type data in C?

We can do this with the definition of an enumerated type, which is a way to define constants, which are incremented by default from 01 times, or are self-defined, and undefined portions are incremented.

2. #include  <stdio.h> &NBSP;&NBSP;
4. #include <stdlib.h>   
5. typedefenum {false= 0,true= 1}BOOL;//Use enum type to define BOOL  
9. int Main ()
11. {
13.      int  k=0x0001;   
15.      bool  i;   
17.      i= (bool ) K; //convert to BOOL takes last
19.      printf ( "%d" Span style= "margin:0px; padding:0px; Border:none; Background-color:inherit; " >,i);   
21.      while (1);   
23. return  0;
25. }
