I've just started learning c++ and am trying to write a semi-complicated console program. Basically it's just a simple label program(well it doesn't do anything yet). The very simple (and hopefully easy to answer question) is how can I iterate over a set of constants without using a variable? All I'm actually trying to do is draw parallel lines at different y or x coordinates with a different number of lines between them. I know I could manually do this, but I'm trying to make things easy to change later. I'm using Dev-cpp 4.9.9.2 and the windows api(if it's not obvious). Below is the basic sort of thing I'm trying to do(although the basic question is something I would like to know the question to regardless). HANDLE winid = GetStdHandle(STD_OUTPUT_HANDLE); COORD home = {0,0}; <iterate over a set of constants(say 2 5 9 18) with variable whatever> { home.Y=whatever; SetConsoleCursorPosition(winid, home); for (int n=1; n<15; n++) { cout << (unsigned char)196; } } Basically I curious as to whether c++ has a function akin to the batch for loop (i.e for %%a in (2 5 9 18) do .....) without using a incrementing for loop over an array. I will use a variable, array or something if I must but it just seems more clutter to set the use once constants to a variable/array just to loop over the set. One more thing, does anyone know how to specify a coordinate as a constant values(i.e SetConsoleCursorPosition(winid, {x,y})) rather than a "COORD" data type?

how can I iterate over a set of constants without using a variable? STL has for_each(). It's handy if you're doing work with an STL container, but I don't know of anything in C++ like CMD's FOR. One more thing, does anyone know how to specify a coordinate as a constant values(i.e SetConsoleCursorPosition(winid, {x,y})) rather than a "COORD" data type? There is no conversion from an array of type short to a COORD, implicit or explicit. I suppose if you wanted, you could make a simple struct derived from COORD, which took two shorts in its constructor. struct coord : public COORD { coord(short x, short y) { X = x; Y = y;} }; Then, you could use temporaries and do SetConsoleCursorPosition(winid, coord(x,y))

Thanks Razor2.3, You've saved me searching endlessly for something that wasn't there. I guess a couple of extra lines won't hurt. I couldn't get that code for coordinates to work because I haven't learnt struts yet. It will hit me over the next week or so.... Your help is much appreciated, top notch as usual.

I couldn't get that code for coordinates to work because I haven't learnt struts yet. They're like classes, only their members are public (vs. private) by default. What's happening when you try it?

Ok I had another look at it(to replicate what I did last time) and it does indeed work. I made the stupid mistake of testing the code right before the code that re-sizes the window, buffer and window again. No wonder it didn't seem to work! Thanks again for your help. [edit] To answer your actual question nothing seem to be happening, the cursor would stay where it was.
