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 #include 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

name.cpp

#include #include using namespace std; #include "name.h"

void name::GetFirst(string str) { str=first; }

void name::SetFirst(string str) { first=str; }

void name::GetMiddle(string str) { str=middle; }

void name::SetMiddle(string str) { middle=str; }

void name::GetLast(string str) { str=last; }

void name::SetLast(string str) { last=str; }

void name::PrintLast() { cout << last << " "; } void name::PrintMiddle() { cout << middle; } void name::PrintFirst() { cout << first; }

name.h

#define LAST "tankengine" #define MI "the " #define FIRST "thomas "

class name {

private: string first; string middle; string last; public: void SetFirst(string str); void GetFirst(string str); void SetMiddle(string str); void GetMiddle(string str); void SetLast(string str); void GetLast(string str);

void PrintLast(); void PrintMiddle(); void PrintFirst(); };

Program: myname Version: 1.1 Created: 9/6/05 Revised: 1/22/09 Files: name.cpp, name.h, main.cpp, Makefile Programmer: Patrick O'Keefe who gratefully acknowledges Dr. Jason Bakos's kind assistance. Course: CSCE-215 Assignment: Class Project Compiler: GNU Gcc version 4.2.3 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
