c++ - What does this code output a smiley face? - 


#include <iostream> #include <string>  using namespace std;  int main(){    string x;    x = not false , true;     cout << x << endl; }

why code output smiley face when ran?

nothing wrong code.

not false , true equivalent !false && true 1.

then use std::string::operator=(char) assign value x. value of 1 char apparently translates smiley on system.
