Testing and Debugging

The Debugger

Modern development environments contain special programs, called debuggers, that help you locate bugs by letting you follow the execution of a program.
You can stop and restart your program and see the contents of variables whenever your program is temporarily stopped.
Using a debugger is not cost free - it takes time to set up and carry out an effective debugging session.
Larger programs are harder to debug without using a debugger, so learn how to use one is time well spent.
