C Projects in Eclipse
- Download Eclipse CDT - from the list choose "Eclipse IDE for C/C++ Developers".
 - Unarchive and run downloaded Eclipse
 - Close "Welcome screen", if you're running Eclipse for the first time

 - Add ... > Workspace...
 - Choose your lab project root folder (lab03)
 - OK, OK, OK
 
Now you should be able to work with your project.
Keyboard shortcuts worth knowing (On MacOS Ctrl must be replaced by Cmd for most of the shortcuts):
- Ctrl+B - build your project. Check Console window for error messages
 - Ctrl+Tab - switch between source and header files (.c and .h)
 - F3 or Ctr+Left click on a function, variable, macro - Open Declaration - go to its declaration/definition. The definition outline will be displayed automatically, if you hold mouse over a function/variable/macro name.
 - Ctrl+H - workspace wide search. Choose "File search". Type in your keyword and file pattern (I use "*.S, *.c, *.h" to search C source/header and ASM files). To avoid annoying C++/Task search, I choose "Customize"in the Search window and uncheck all the unnecessary alternatives, leaving only "File Search" checked.
 - Ctrl+Shift+G on a variable/function - Open Call Hierarchy - show all places where it is used/called. Very useful to check, where a variable is initialized and modified
 
All these commands are also available in the context menu - right click and choose it from the menu.
