chmod +x makes a file executable. This needs to be done for python executables and shell scripts.

What you have is a C++ program that you need to compile. This will then create an executable in the devel space that is by default executable.

if you haven't called catkin_make/catkin build in your workspace or if there have been any error messages, this is the problem that you are seeing.

Please follow this tutorial as well as this one to understand how to compile a workspace with a C++ node.
