Question

This is an assignment done using the terminal of linux.

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.

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”

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

Submission This time, there should be two files that you are uploading

[yourUserID].assingment4_1.tar.[Z,gz] and [yourUserID].assingment4_2.txt

• When you have finished, submit the files using the departmental dropbox.

Here are the contents of CSCE215 directory that contains the program and files associated with it:

main.cpp

#include <iostream>
#include <string>
using namespace std;
#include "name.h"

int main () {
        name myName;

        myName.SetLast(LAST);
        myName.SetMiddle(MI);
        myName.SetFirst(FIRST);

        cout <<"My name is: ";
        myName.PrintFirst();
        myName.PrintMiddle();
        myName.PrintLast();
  
        return 0;
}

Makefile

# makefile to build a program

# program depends on components: name and main
myname:      main.o name.o
   g++ -g main.o name.o -o myname

# name.cpp has it's own header file
name.o:        name.cpp name.h
   g++ -c -g name.cpp

# main.cpp also uses the header file name.h
main.o:           main.cpp name.h
   g++ -c -g main.cpp

clean:
   /bin/rm -f myname *.o

Target: Linux

Description:

This program attempts string assigment. and other stuff....

Revisions:

There have been no major revisions of this program.

Constants and Variables:

See code for constant and variable descriptions.
or
you could put that kind of info here. Like:
   FIRST -> your first name
   MIDDLE -> ditto
   LAST -> and ditto.
ok here is a change.

ALL OF THOSE FILES ARE LOCATED IN A DIRECTORY /CSCE215

//main.cpp
#include <iostream>
#include <string>
using namespace std;
#include "name.h"

int main () {

cout <<"My name is: ";
myName.PrintFirst();

myName.PrintLast();
  
return 0;
