Testing and Debugging

The Debugger

Debuggers vary wildly from one system to another.
If you use an integrated development environment, which contains an editor, compiler, and a debugger, finding and starting the debugger is usually very easy.
On a UNIX system, you must manually build a debug version of your program and invoke the debugger.
You can go a long way with just three commands:
- Run until this line.
- Step to next line.
- Inspect Variable.
The exact names for these commands will vary from debugger to debugger, but all debuggers support them.
