ok so i'm programming with dev-c++ and i cant think of anyway to make this
not flicker like it does. all i know is to do it like this i wouldnt know
how to JUST clear the player and not the screen any help would be great thanks
in advance. and i know im using printf but its still in c++
this is my code
i dont want to continue any further with the game until i stop the flickering

Try using C++.

Try using C++.

It's not an issue with C programming, it's an issue with clear screen. Everytime you clear the screen, it will essentially move the cursor to the top, press space a lot of times, and then move the cursor back to the top. You then tell the computer that after it does all of that really fast, you want it to print out all of your text really fast. This causes the "flicker" that you see.

Work arounds: There really isn't any, but instead of using clear screen, display 25-30 new lines ("\n") to effectively scroll the console up, then display your new stuff. This should also be a little faster and less CPU intensive. Simply, clearing the screen isn't a pretty thing.

Edit: Also, using system is horribly bad practice, do not get used to it. I'll post the link if you actually care, but I, along with just about everyone else on this site, will strongly urge you against it.

You should not use system to substitute for your lack of knowledge of C++. There is many workarounds for the same exact things you want to do, you just need to learn them.
