Function Default Values

[shrewd fern]

I have 2 default values but how should I fill up the last one?

void drawVerticalLine(int length, string filler=BH, string corner=BC);

drawVerticalLine(69, corner=420);

[olive lichen]

what is "BH"

you only have to pass the parameter if you want to change it

In C++, you don't name the parameters during the call. You just fill them in order:
drawVerticalLine(69)
drawVerticalLine(69, "BH")
drawVerticalLine(69, "BH", "420")
