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

How to get help?

Ask questions in class (or after class) Attend office hours Email 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 email

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

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

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 <iostream>

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 literalsend 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

Expanding if Statement36

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
