    Which compiler is currently able to compile this two code snippets:

    std::vector<int> v = {1, 2, 3, 4, 5};
    std::println("{}", v);


    Suppose you want it to be centered in a line of 40 characters, with
    underscore characters around it:

    std::vector<int> v = {1, 2, 3, 4, 5};
    std::println("{:_^40}", v);
    // ____________[1, 2, 3, 4, 5]_____________

    Thank you for reading this and possible solution.

    g++ 13.2.1 does not compile.

    IMO, such funciion is unnecessary, esp. inventing it to add burden to programmer.

    There are lots of I/O formatting problems.
    The basic solution is writing your own 'printf', or atoi,... (all are simple)

    There are already lots of printf examples for students, why this 'new' one?


    He's asking us to do his homework.
