計算機程式設計 (Computer Programming)

We start with basic programming concepts that correspond to chapter 1, 2, 3 of the book. We will start with a basic program and gradually add computation statements so that our program will perform useful computation. Also we will use an online interface (ideone) to describe the process of editing, compiling and running a program.

The second week will describe flow control and loops (book chapter 4, 5). After we learn how to write a program to perform basic computation in the first week, we start to learn the control structure of a program. We will learn how to control the execution of a program among several possible "next steps", and how to repeat the computation to finish repetitive tasks. We will also describe certain loop ending practice, which strongly relates to programming style.

The third week describes arrays and floating point numbers (book chapter 6, 7). We will introduce ways to organize related data into the most basic data structure, i.e., array. We will describe the circumstance of using an array, and the most useful idioms in using them. Various examples will be introduced to enforce the concepts in using array correctly. We will also describe the concept of floating point numbers, which is different from the integers we introduce at the beginning of this course.

The fourth will will describe the concept of functions (book chapter 8). We will motivate the use of function by system functions, including mathematic and input/output functions, so we the students can understand the key concept that if we can use existing code, then we do not need to reinvent the wheel. Then we will introduce the way to define our own functions. The key mechanism of function call, parameter passing, and return values wiill be discussed by a series of examples.
