Introduction

The type _Bool stores Boolean values.

A Boolean value typically comes from a comparison where the result may be true or false.

The value of type _Bool can be either 0 or 1, corresponding to the Boolean values false and true, respectively.

Because the values 0 and 1 are integers, type _Bool is regarded as an integer type.

Demo Code

#include <stdio.h> 
int main(void) { 
  bool valid = 1;                            // Boolean variable initialized to true
  
  printf("%d",valid);
  
  return 0; /*from  ww  w . ja v  a 2 s .c om*/
}

Result

You can assign integer value to _Bool type value.

Demo Code

#include <stdio.h> 
int main(void) { 
  bool valid = 123;                            // Boolean variable initialized to true
  
  printf("%d",valid);
  return 0; /*from  w w w .  jav a  2s .  c  o  m*/
}
