3. Course Information Lectures –M,T,W,F 1-1:50pm, Tech. LR4 –Tuesday meetings: TA sessions Text –C++ How to Program, 3 rd (or 4 th ) Edition, by H.M. Deitel and P.J. Deitel, Prentice Hall. Course Web –http://www.courses.nwu.edu/ (NU Black board) using your IDhttp://www.courses.nwu.edu/ Grading –Machine Problems (MPs):30% –Midterm exam: 30% –Final exam:40%

4. Why should we study programming? Think about your new role in 5 years –A graduate student –An engineer –A manager – … Programming practice can –Implement your ideas –Motivate you to re-think your ideas –Make you solid, sharp and deep-thinking –Make you more cooperative

5. Eager to Learn C/C++? We shall cover –C/C++ control structure –Function –Pointer and Array –Stream I/O and string operations –Dynamic memory allocation –Class –Classes with pointer data members –Link list –Sort and search See the course syllabus for a detailed schedule

6. We’ll focus on Core C/C++ concepts –Such as: Pointers and references Call-by-value v.s. call-by-reference Class Copy constructor … Debugging skills

7. How do we learn it efficiently? Do and Make your code Work! In this course, you will build a working system: the MiniMatlab Project Through each lecture, you will learn some useful stuff and make a small tool or library The machine problems (i.e., MPs, or assignments) are progressive. You will start from scratch, but you may end up with hundreds of lines of code! Last, you will put together the tools you’ve made and build a “big” working system

8. The MiniMatlab Project Stream I/O Command Line Interpreter System Variable Database Arithmetic/Logic Unit Database management Array/Matrix
