how do I get my eclipse CPP lunar to show ouput?

I just installed Eclipse CPP lunar for my windows 64, and I ran a couple of C code (not c++), but for some reason I can get to the console to show any output, I did the build PATH in the environment part in my properties, but still can't get anything to show. I run my C code in cmd, and everything was perfect! what should I do? do I need to add new flags, it seems the code can run well just no ouput.

update: I watched a video on youtube, and I run some c++ code and the output console is perfect for some reason, just C code I can't get any output. did I built the path wrong?
