    설명

    불 리터럴은 키워드 true와 false이다. 이들은 불 유형 prvalues이다.

    Notes

    예시

    코드 실행 
    #include <iostream>

int main()
{
  std::cout << std::boolalpha
            << true << '\n'
            << false << '\n'
            << std::noboolalpha
            << true << '\n'
            << false << '\n';
}

    Output: 

    true
false
1
0
