Using the GCC compiler in Ubuntu: no file or directory

(1) When we compile the code, we usually encounter the following error

But we do see that my files are there!

The question is what that:

A. Your own directory is really wrong, this only need to modify the directory can be, not to say;

B. One of the most covert is the problem that occurs when the file is named, as follows.

Above this is the normal naming, when the mouse on the suffix behind the time, is close to;

And you see, this is the suffix you just didn't find. There is a space behind it! Nima is too hidden! The problem has been found to remove the space just fine!

Ok! Can look at the effect!

To explain the problem more effectively! We put the top two test files in the Windows directory, and then we can see why! OK hope to help you!
