false (C+)
The keyword is one of the two values for a variable of type bool or a conditional expression (a conditional expression is now a true Boolean expression). For example, if i is a variable of type bool, the i = false; statement assigns false to i.
Example
// bool_false.cpp
#include <stdio.h>
int main()
{
bool bb = true;
printf_s("%d\n", bb);
bb = false;
printf_s("%d\n", bb);
}
