    string v.s. basic_string

    Hello everyone,


    I would like to learn some experiences about when should we use std::basic_string and when should we use std::string?

    I learned some Hello World level samples and now want to listen to your practical experiences. :-)


    thanks in advance,
    George

    So, essentially, you are using "basic_string" when you are using string or wstring.

    Always use string unless you know why you want to use basic_string.

    I used basic_string a little while ago with a Windows app.
    I just made a typedef of basic_string<TCHAR> so it could be compiled as either ASCII or Unicode...

    Other than that, I don't know any other reason you'd need to use basic_string?

    Yes, that would be a good use-case.

    In fact, where I work, we have a similar concept where the "string" class is automatically unicode or ASCII/ANSI depending on a switch.
