C++ String Comparison "Good Luck" > "Good Bye"

Question

I am comparing two strings "Good Luck" > "Good Bye" in c++. Shouldn't the boolean result be true? The 'L' is greater than the 'B' The blank space between the words is one whitespace.

However, I am getting false with run the code.

Do you know why? Below is my code.

#include <iostream>

using namespace std;

int main()
{

    bool result = "Good Luck" > "Good Bye!";

    cout << result;

    return 0;
}

This is what the documentation says - s1 > s2 : A string s1 is greater than s2 string, if either, length of s1 is longer than s2 or first mismatched character is larger — Avi, Mar 25 '18 at 16:34
@Avi but you are *not* comparing `std::string`s. You are comparing `const char *`s. — Jesper Juhl, Mar 25 '18 at 16:40
@Avi Whatever document you are reading, make sure what you read is relevant to what you use. I rephrase: String literal is not `std::string`. — , Mar 25 '18 at 16:41

You're comparing char*s, which is just comparing the memory addresses that the strings live at.

The documentation differs -- s1 > s2 : A string s1 is greater than s2 string, if either, length of s1 is longer than s2 or first mismatched character is larger – Avi Mar 25 '18 at 16:35

@Avi: That's the documentation for `std::string`, which you are not using. – SLaks Mar 25 '18 at 16:36

@Avi I repeat: Distinguish C-string and `std::string`. – Mar 25 '18 at 16:37
