Is there a project for beginners that could take a little bit of time that would teach them alot about coding? Maybe give some ideas so i know what i can do and plan it out. Right now i have learned:
cin
cout
if
case
switch
system
variables
strings/chars
fstream
while loops
messageboxes
error fixes
putting it together
some other things i cant remember.

If you have anything i can learn to do that would be greatly appreciated.
