[edit] Syntax


true	(1)

false	(2)

[edit] Explanation

boolean true (value of 1)
boolean false (value of 0)

[edit] Example

std::cout << std::boolalpha
          << true << '\n'
          << false << '\n'
          << std::noboolalpha
          << true << '\n'
          << false << '\n';

Output:

true
false
1
0
