How to enable Eclipse to autobuild/autosave change

问题:

I'm trying to conveniently have the updated code in effect when I click the run button in Eclipse. At present it will run the last build and I have to manually click build before clicking run to see the changes.

Can someone advise me on how to configure Eclipse to autobuild the current project (if changes has been made) before running the code?

If you want to automatically build your project on save (or before run, if needed), then from tool-bar menu go to

Project -> Properties -> C/C++ Build -> Select Behaviour Tab on the right panel, -> tick the "Build on resource save(Auto build)" , finally hit OK

That is it...
