How do I compare strings in C++20 using std::string?

How do I compare strings in C++20 using std::string?

In C++20, you can compare strings using the relational operators like ==, !=, <, >, <=, and >= directly on std::string objects.

Can you show me an example of string comparison?

Sure! Here's a simple example:

#include <iostream>
#include <string>

int main() {
    std::string str1 = "Hello";
    std::string str2 = "World";

    if (str1 < str2) {
        std::cout << "str1 is less than str2";
    }
    return 0;
}

What about case sensitivity in string comparison?

String comparison in C++ is case-sensitive by default. To perform a case-insensitive comparison, you can convert both strings to the same case using std::transform.

Is there a way to compare substrings?

Yes, you can use the substr() method to extract substrings and then compare them using the same relational operators.
