PART $2$ GDB

Program etox.c should approximate ex but has an error that makes it execute incorrectly. First, simply compile and run the program to observe the incorrect behavior, then recompile it to support debugging with gdb and use the gdb commands to identify the source of the incorrect behavior. Lastly, fix the errors and run the program to observe the correct behavior. Record all the gdb activity.
