Remove n characters from console

I'm writing a program in D that doesn't need a GUI. I remember that in C++, there was a way to remove a number of characters from console/terminal, but I don't know how to do this in D. How do I remove a number of characters from the console/terminal?

Solution

    Do you mean getchar? You have direct access to the entire standard C library in D. For example have a look at this simple script:

    void main()
{
    import core.stdc.stdio : getchar;
    foreach(i; 0..3)
        getchar();

    import std.stdio;
    writeln(readln());
}

    When you compile & execute this script (e.g. here with rdmd)

    echo "Hello world" | rdmd main.d

    it would print:

    lo world

    But I have to agree with Adam that just slicing readln is easier and looks nicer ;-)
