1. COMP2012H: OOP and DS (honors track)
Fast-paced
High workload
Learn many details on your own
Therefore, you must be both good and hard-working to succeed
COMP2012H challenges the best and the most independently minded!

2. Announcement No lab in week 1
Want to skip all the labs: score them all before Mar 4! See courseweb for details.

3. Hello World! #include <iostream.h> using namespace std;
int main() {
cout << "hello, world!" << endl;
return 0; }
contains classes/objects
useful for screen output
e.g. cout

4. Who wants to write this … except COMP180 students ?!
org 100h
; set video mode
mov ax, ; text mode 80x25, 16 colors, 8 pages (ah=0, al=3)
int 10h ; do it!
; cancel blinking and enable all 16 colors:
mov ax, 1003h
mov bx, 0
int 10h
; set segment register:
mov ax, 0b800h
mov ds, ax
; print "hello world"
; first byte is ascii code, second byte is color code.
mov [02h], 'h'
mov [04h], 'e'
mov [06h], 'l'
mov [08h], 'l'
mov [0ah], 'o'
mov [0ch], ','
mov [0eh], 'w'
mov [10h], 'o'
mov [12h], 'r'
mov [14h], 'l'
mov [16h], 'd'
mov [18h], '!'
; color all characters:
mov cx, 12 ; number of characters.
mov di, 03h ; start from byte after 'h'
c: mov [di], b ; light red(1100) on yellow(1110)
add di, 2 ; skip over next ascii code in vga memory.
loop c
; wait for any key press:
mov ah, 0
int 16h

COMP180 students ?!

5. What’s good about OOP? Objects separate interface from implementation
In C++, interface is given by .h files, and implementation by .cpp files

6. Suggested Work Schedule for Project #1
Due on Mar 8!
(14 days) work up to lab5.
Learn QT / some inheritance on your own
(14 days) work on project #1.
OOP allows you to implement the requirements readily by using QT classes
(4 days) backup
in case you fall short of the above schedule

7. Due dates and late penalty
Projects are due at 23:59:00 on the due date. You are permitted a total of five late days without penalty for the semester that may be used on any of the five programming projects.
