The message is telling you what is wrong; what is it about "No such file or directory" that you do not understand? Given this and your other questions, I strongly recommend you get hold of a decent reference on C programming. You cannot expect to learn it by asking repeated questions here.

but it is inside the directory that wat i was asking is it due to logical error or wat?

Are you sure that your project configuration includes that directory in its search path?
