c program run on codeblocks but not on clion how is it even possible?

i successfully run it on codeblocks, but my clion doesnt display anything when i run it.
i usually use clion, so im very furious about this. (dont want to be obligated to use codeblocks)
please help a poor lost soul.
this is the code.

dont have a lot more to say, but still stackoverflow wants me to write more, so here i am.

#include <stdio.h>
#include <stdlib.h>
