GDB (Gnu DeBugger) Resources
GDB is an immensely useful tool to help you debug your C programs. It lets you insert breakpoints into your programs so that you can stop execution and examine the contents of memory and registers. It also supports single-stepping your program one line of source code at a time. It leads to much more productive debugging than just using printf. The time you spend getting familiar with GDB will be an excellent investment.
