What are some useful string functions in C++17?

C++17 introduced several useful string functions. For example, you can use std::string::starts_with and std::string::ends_with to check prefixes and suffixes.

Can you give me an example of how to use starts_with?

Sure! Here's a simple example:

#include <string>

int main() {
    std::string str = "Hello, World!";
    if (str.starts_with("Hello")) {
        std::cout << "String starts with 'Hello'";
    }
}

What about string::contains? Is that available in C++17?

Actually, std::string::contains was introduced in C++20, not C++17. In C++17, you can use std::string::find to check for substrings.

Thanks! Are there any other notable string features in C++17?

Yes! C++17 also introduced std::string_view, which allows for non-owning views of strings, improving performance in some cases.
