The code can be downloaded here and a simple Makefile for the program can be downloaded cpp tutorial deutsch. The code is very simple and consists of two class definitions, a node and a linked list.
There is also a simple driver to test the list. All of the code was placed into a single file to make illustrating the process of debugging a little easier. Preparations Environment settings gdb is in the gnu package on CEC machines.
If you don't have this package loaded then type pkgadd gnu at a shell prompt. For Sun CC users, there is cpp tutorial deutsch dbx debugger which is very similar to gdb. For even more information, the -ggdb switch can be used which includes cpp tutorial deutsch symbols which are specific to gdb.
The makefile for this tutorial uses the -ggdb switch. Debugging When to use a debugger Debugging is something that can't be avoided.
Every programmer will at one point in their programming career have to debug cpp tutorial deutsch section of code. There are many ways to go about debugging, from printing out messages to the screen, using a debugger, or just thinking about what the program is doing and making an educated guess as to what the problem is.
Before a bug can be fixed, the source of the bug must be located. For example, with segmentation faults, it is useful to know on which cpp tutorial deutsch of code the seg fault is occuring.

Once the line of code in question has been found, it is useful to know about the values in that method, who called the method, and why specifically the error is occuring. Using a debugger makes finding all of this information very cpp tutorial deutsch. Go ahead and make the program for this tutorial, cpp tutorial deutsch run the program.
The program will print out some messages, and then it will print that it has received a segmentation fault signal, resulting in a program crash.
Given the information on the screen at this point, it is near impossible cpp tutorial deutsch determine why the program crashed, much less how to fix the problem.
Cpp tutorial deutsch will now begin to debug this program. Loading a program So you now have an executable file in this case main and you want to debug it.
First you must launch the debugger.

The debugger is called gdb and you can tell it which cpp tutorial deutsch to debug at the shell prompt. So to debug main we want to type gdb main. Here is what it looks like when I run it: Type "show copying" to see the conditions.
There is absolutely no cpp tutorial deutsch for GDB. Type "show warranty" for details. This GDB was configured as "sparc-sun-solaris2.
If you are using Emacs, you can run gdb from within Emacs by typing M-x gdb. Then Emacs will split into two windows, where the second window will show the source code with a cursor at the current instruction.

I haven't actually used gdb this way, but I have been told by a very reliable source that this will work. We need to run the program so that the debugger can help us see what happens when the program crashes. Type run cpp tutorial deutsch the gdb prompt.
Here is what happens when I run this command:
