The graphically based debugger environment is part of what is called the Integrated Development Environment IDE The purpose of these notes is to introduce you to this environment and help you learn how to use it as you develop and hone your programming skills A debugger cannot solve your problems for you It is merely a tool to assist you when programming You should first attempt to read over your code and using paper and pencil analyze the code to get an understanding of what is going on Once you have gotten an idea of where in your code you have an error you can then set the debugger to watch certain variables in your program Watching your code will show you step by step how your program is being executed The debugger that you will use is part of an Open Source free IDE called Code Blocks which we have found easy to use and is described in these notes Code Blocks has a C editor and compiler It will allow you to create and test your programs from one easy to use application We hope these notes will assist you in making programming more enjoyable and help you develop better programming skills You may find additional information regarding Code Blocks at http www codeblocks org A complete manual for Code Blocks is available here http www codeblocks org user manual 3 of 64 Installation of Code Blocks Step 1 Download the Software In order to install the Code Blocks IDE as well as the MinGW compiler you must download i
