All of this should be able to be done in a linux terminal.

Overview: In this assignment, you will

use make to modify a c++ program and

gdb a debugging tool.

Part 1 From the course website (or the departmental dropbox) download the program source files for the project myname. (provided below)

Part 2: myname program (5 points)

1. Using your favorite text editor, modify the source code to print out your name instead of mine when the binary file is executed. Hint: YOU ARE NOT THOMAS THE TANK ENGINE (make of comment of where you change this so I can change it to my name please)

2. Modify the makefile to include a rule that creates a backup of the source files, makefile, and readme in an archive directory in your home directory structure. Submit a compressed, archived tar file [yourUserID].assignment4_1.tar.[Z,gz] with your modified source code.

3. Use the gdb debugger to step through the program. Check to ensure the Makefile is modified to allow for debugging. Submit a text file [yourUserID].assignment4_2.txt containing the gdb output for the following sequence of commands:

gdb myname

start

step [issue this command until you get the program exited normally message]

quit
