C Booleans

C- booleans are a data type in the C Standard Library which can store true or false. Boolean contains two types of values, i.e., 0 and 1. , the bool type value represents two types of behavior, is true or false. ‘0’ represents false value, while ‘1’ is represents the true value. In C Boolean, ‘0’ is stored as 0, and another integer is stored as 1.

C boolean Syntax

bool variable_name;

Example of C booleans

#include <stdio.h>  
#include<stdbool.h>  
int main()  
{  
bool x=false; // variable initialization.  
if(x==true) // conditional statements  
{  
printf("The value of x is true");  
}  
else  
printf("The value of x is FALSE");  
return 0;  
}

Print boolean c

The value of x is FALSE

Boolean Expressions

The expression which returns boolean values: 1 (true) or 0 (false) value is called boolean expression. In the following example, using the comparison operator in the boolean expression which returns 1 when left operand is greater than right operand else returns 0.

Program for boolean expressions

#include <stdio.h>

int main (){
  int x = 10;
  int y = 25;

  printf("%i\n", (x > y)); //returns 0 (false)
  return 0;
}

Output
