Why can't I run even system("cls") in Code Playground?

Question

Even if the console had just this function, Some of my C++ codes would become a lot better than before.

Is there any alternative that I can use here?

Answer 1

What system("cls") actually does is calling the CLS (CLear Screen) command in Windows CMD (Command Prompt). Therefore there's no way to replicate this behaviour in Code Playground to my knowledge.

P/S: Try type "cls" without quotes in Windows CMD and you'll get what I mean.

Answer 2

I realize now that they don't want people messing with the server. But if they can't give cls, can't they give us a cursor setting function like SetConsoleCursorPosition() from windows.h?

//BTW, <windows.h> can be included here on SoloLearn, plus its functions are even recognized by the intellisense part of CodePlayground, and those functions just don't work as expected.

// Plus those functions don't even return errors...
