    However, I'm fairly sure C++ does deal with const const int by collapsing it to const int. For example:

    Well, it must be possible, but I'm guessing it'd be pretty complex unless there's some library out there. Why do you want to use the excel file directly?

    Not sure how you would do this directly. However you can save excel files with a single sheet to .csv, which would convert a sheet that looks like this:

    Why? If 3 was a const int then we would have [T = const int]:

    void foo(const int&) { }

    Unless the compilation of this code is also strange to you:

    Literal ints are non-const?

    Could someone please explain to me why a literal integer is an rvalue of type int instead of an rvalue of type const int?

    In particular, it creates this strange situation:

    As Nor pointed out that "if" should be "for". However there is another problem here. Notation in maths often gets sloppy, and a < x < b meaning x is between a and b is a good example of this.
