CSU Honor Code  The Honor Code applies to your conduct in this course. If you have questions, talk to me  HOMEWORK:  All submitted work must be your own  Do not copy another student’s work  Do discuss material and homework with classmates, professor  If you work with someone, write this on the first page of your submitted work  EXAMS: Do not give assistance to or receive assistance from anyone but professor  Violations of this Code are treated seriously  Evidence of cheating, plagiarism, or unauthorized collaboration will result in a 0 grade for quiz/assignment/exam  May have further consequences 7

How to get help?  Ask questions in class (or after class)  Attend office hours  me  Make sure that you put “CPS1192” in your subject line  Send it from your.odu account It wouldn’t come to my spam folder  State clearly what you need in your 8

How to Get an A in this Class  Attendance  Attend class regularly and on time  Ask questions  Work on in-class exercises and lab assignments  Notes  Read over class notes before class  Review class notes after class  Homework  Get started as early as possible  Contact me if you encounter problems 9

What You Will Learn  CPS 1192 prepares students for the concept and skill of object-oriented programming (OO).  Topics include class and object, class inheritance, pure virtual function, polymorphism, template function and template class, exception handling, data structure 10

What You Will Learn-cont.  Upon successful completion of this class, you will be able to define and implement  Classes  Array of objects  Class Inheritance.  Pure virtual function and abstract class.  Polymorphism.  Template function and template class.  Exception handling  Data structure: stack, queue and linked-list. 11

Topics  C++ programming Overview  Classes and Data Abstraction  Inheritance and Composition  Pointers, Classes, Lists, and Virtual Functions  Overloading and Templates  Exception Handling  Recursion  Linked Lists  Searching and Sorting Algorithms  Stacks and Queues 12

Importance of This Course  Prerequisite for  You must get a C or better to pass  Foundation for advanced courses  Operating Systems  Programming Language  Compiler Design  Networking  Parallel Programming  Algorithm  I/O Management 13

About Me  I got my bachelor’s from JUST (Jordan University of Science & Technology)  Master’s from NYiT (New York Institute of Technology)  Ph.D. (in process) ODU (Old Dominion University)  My Research  Computational Biology  High Performance Computing 14

How about you? 15  Tell us your name and year  In a few sentences, tell us about you, e.g.  Where are you from?  What is your major?  Career plans or after-college plans?  Favorite hobby, sport?  Something interesting about yourself  Expectation in this class

Greater Expectations  Class Attendance & Participation: mandatory  In-Class exercises/discussion questions Solidify your understanding Help gauge your understanding Increase interactivity (reduce boredom)  You are expected to try your best in class  By attending, you work less out class.  If you miss class, you are responsible for learning what you missed 16

Greater Expectations-cont.  Behave and perform in a professional manner  Be punctual, dress appropriately and be attentive  Respect the rights of all participants by turning off any device that could cause a disturbance during class (this includes pagers, cell phones, personal alarms and iPod music players).  Negative behavior patterns in class (e.g. unexcused absences, tardiness, and class disruptions, wearing hats, eating, drinking, smoking and sleeping) will be treated seriously  could result in a reduction of up to 12.5% (labs) of a student’s final grade. 17

While in Class,  No Facebook  No Cell phone  No Music players  No Topic unrelated to class.  No Sleep  No Food  No bad jokes 18

Overview of CPS 1192: Programming in C++ 19

Chapter 1: Introduction to Computers and Programming  A program is a set of instructions that the computer follows to perform a task  An integrated development environment, or IDE, combine all the tools needed to write, compile, and debug a program into a single software application.  Examples are Microsoft Visual C++, Turbo C++ Explorer, CodeWarrior, etc 20

What is a Program Made of?  Common elements in programming languages:  Key Words  Programmer- Defined Identifiers  Operators  Punctuation  Syntax 21

Chapter 2: Introduction to C++ 22 // sample C++ program #include using namespace std; int main() { cout << "Hello, there!"; return 0; } preprocessor directive comment which namespace to use beginning of function named main beginning of block for main output statement end of block for main string literal send 0 to operating system The Parts of a C++ Program

cout/cin, include  cout/cin  cout << "Programming is" << endl; cout << "fun!";  int grade; cin>>grade;  #include Directive 23

Variables and Literals 24

Identifiers 25 IDENTIFIERVALID?REASON IF INVALID totalSales Yes total_Sales Yes total.Sales NoCannot contain. 4thQtrSales NoCannot begin with digit totalSale$ NoCannot contain $

Data Types & Defining Variables 26

Variable Scope 28

Chapter 3: Expressions and Interactivity  Cin Object Reads Different Data Types  Mathematical Expressions  Order of Operations  Algebraic Expressions 29

Type Casting 30

Combined Assignment Operators 31

Formatting Output  Stream Manipulator 32

33

Mathematical Library Functions  Require cmath header file  Take double as input, return a double  Commonly used functions: 34 sin Sine cos Cosine tan Tangent sqrt Square root log Natural (e) log abs Absolute value (takes and returns an int)

Chapter 4: Making Decisions  Relational Operators >, =, ==, !=  Do not confuse = and ==  Relational Expressions  The if Statement 35

Expanding if Statement 36 Nested if Statements if/else if Statement

Logical Operators, AND, OR, NOT  int x = 12, y = 5, z = -4; 37 (x > y) && (y > z)true (x > y) && (z > y)false (x <= z) || (y == z)false (x <= z) || (y != z)true !(x >= z)false

switch Statement 38

Chapter 5: Loops and Files 39

While loop 40

Do-while 41

For loop 42

Nested for Loop Inner Loop Outer Loop Breaking and Continuing a Loop

Using Files for Data Storage 44
