7	Grading
8	Grading Scale
9	Calculating Grade [Your points]/[Total points] * [Weight] 90/100 * .60 = .54 10/10 * .20 = .20 5/10 * .10 = .05 lab = .05 hw = .05 Total = 89%

12	What are we doing?
13	The Development Environments Popular IDEs/Compilers Microsoft’s Visual C++ 2008 Express Edition http://www.microsoft.com/express/download/ Microsoft’s Visual C++ 2005 Express Edition http://msdn.microsoft.com/vstudio/express/visualc/default.aspx GNU’s g++ with a text editor of choice http://gcc.gnu.org/ Borland’s C++ builder http://www.codegear.com/tabid/123/Default.aspx MinGW http://www.mingw.org/ Dev-C++ (BloodShed) http://www.bloodshed.net/dev/devcpp.html
14	What environment will we use? We will use the linux operating system with the GNU g++ compiler. You can use any editor you like linux provides nano, vim, emacs You must compile your programs and execute them on the fccsci.fullcoll.edu server to receive full credit
15	Text Editors Windows Editors Vim http://www.vim.org/ Notepad++ http://notepad-plus.sourceforge.net/uk/site.htm Linux Editors Nano http://www.nano-editor.org/ Vim http://www.vim.org/download.php

17	Hardware (computer systems) PC (Personal Computer) Workstation Mainframe
18	Network
19	Common Components
20	Computer Memory Main Memory Scratch Paper Temporary Secondary Memory Disk Drives, USB Drives Extended life
21	Main Memory Random Access Memory (RAM) Bit – binary digit Byte – eight bits Address
22	The Computers Brain CPU Basic instructions Add Subtract Multiply Divide Move things
23	Software Operating System DOS, Windows, Linux, Unix, VMS, MacOS, and more… Applications Console, Web Browser, Office Suite, Email Client, Utilities, and much much more…
24	Programs/Applications
25	Languages
26	High Level Languages Examples C/C++ Java C# Visual Basic Look similar to English Easier to write than low level language Must be translated or interpreted into low level language by the compiler Abstracted from the computer hardware
27	Low-Level Languages Close to the hardware Assembly Language Abstract machine language one level Easier to write than Machine language Machine Language CPU understands 100011 00011 01000 00000 00001 000100
28	Compilers Program which takes your source code and translates it into machine code Computer understands the machine code and can execute it on the platform
29	Linker Run after the compiler Combines your object code with any of the pre-existing object code (input and output) generates a complete program
30	Algorithms Sequential steps for solving a problem or task Language independent Written in plain English Allows programmers to concentrate on the solution without worrying about the implementation details
31	Cake Algorithms Stir into a large mixing bowl 2 eggs 4cups of water Cake mix Once all the lumps are gone Preheat oven to 400 degrees Place cake mix in a 4X7 greased cake pan Bake for 35 minutes Cool for 15 minutes and serve
32	Simple Sort Algorithm Get a list of unsorted numbers Repeat steps 3 through 6 until the unsorted list is empty Compare the unsorted numbers Select the smallest unsorted number Move this number to the sorted list Remove the selected smallest number from the unsorted list Stop
33	Simple Sort Algorithm
34	Simple Sort Algorithm
35	Simple Sort Algorithm
36	Simple Sort Algorithm
37	Simple Sort Algorithm
38	Simple Sort Algorithm
39	Simple Sort Algorithm
40	Simple Sort Algorithm
41	Program Design Problem Solving Phase Algorithm is design Algorithm is tested Implementation Phase Algorithm is translated into C++
42	Object Oriented Programming Objects are designed to simulate real world items Objects have characteristics and actions Not specific to C++ C#, PHP, Python, Java and more Main Characteristics Encapsulation Inheritance Polymorphism
43	Software Life Cycle (Common) Analysis and specification of the software Design of the software Implementation Testing Maintenance and evolution of the software Retirement Others Waterfall Model Spiral Model Iterative Model
44	Intro to C++ Derived from C Developed at AT&T Bell Laboratories by Bjarne Stroustrup in the 80’s Overcome some of the shortcomings of C Object Oriented was the one of the main features of the language
45	Sample C++ Programs #include <iostream> using namespace std; int main() { return 0; }
46	Sample C++ Programs #include <iostream> using namespace std; int main() { cout << “Sending text to the screen.\n”; return 0; } cout – sends output to the monitor “\n” – sends the cursor to the next line (newline) return 0; - terminates the program << - insertion operator
47	Sample C++ Programs #include <iostream> using namespace std; int main() { int someInteger = 0; cout << “Declaring variables. Type a number.\n”; cin >> someInteger; cout << “Here’s your number “; cout << someInteger; cout << endl; return 0; } cin – sends input from the keyboard to a variable endl – sends the cursor to the next line (newline)
48	Simple C++ Program Layout #include <iostream> using namespace std; int main() { variableDeclarations ... statement1 statement2 ... return 0; }
49	Compiling and Running C++ source code is text. It can be written with any text editor: VIM EMACS Nano More… This is old school and still cool!!!
50	Compile from Command line G++ Compiler g++ -Wall hello.cpp -o hello Run by typing: ./hello Visual Studio Command line Cl –nologo –Ehsc –GR –Zc:forScope –Zc:wcar_t –Fohello hello.cpp
