    Lightbulb Create folder from variable name

    Hi all

    I have searched for this answer but can't find any posts regarding this particular problem.

    I want to create a folder based on a string variable that I have assigned, but cannot figure out how. There are many examples using functions such as:
    system("MD NewFolder") or
    mkdir("NewFolder) etc

    However I want the name of the folder to be based on a string variable that I have assigned e.g.

    string fldname = "XYZ";
    mkdir(fldname);

    however this gives an error...
    main.cpp cannot convert `std::string' to `const char*' for argument `1' to `int mkdir(const char*)'

    Could someone please give me an idea of how I should go about this. Another point to note - I am writing this on a windows platform, but will then need to compile on UNIX so the system() function would need to be modified if I go with that solution.

    Thanks

    The c_str() function returns a const char*
    Code:
    std::string fldname = "XYZ";
    mkdir(fldname.c_str());

    I believe mkdir is not a standard function. I think it's a UNIX function, and you have to include <sys/stat.h>.

    If you're on Windows, you can use the CreateDirectory function.
