Document Content and Description Below

1. Introduction and Teaching Suggestions This chapter introduces the students to the history of the C++ language and begins to tell them about what types of programs can be written in C++ as well a... s the basic structure of a C++ program. During the discussions on compilation and running a program, care should be taken to explain the process on the particular computer system that the students will be using, as different computing/development environments will each have their own specific directions that will need to be followed. In the development of this instructor’s manual, a majority of the programs have been compiled using g++ 4.0.2 on Ubuntu Linux, g++ 3.4 on cygwin, and Visual Studio .NET 2008 using Windows Vista. There are significant differences between the development environments and sometimes on the compilers as well. Anyone that is still using Visual Studio 6 is strongly recommended to upgrade to the latest patch level, as the original compiler contained many errors that will prevent programs in this book from compiling. Simple programming elements are then introduced, starting with simple variable declarations, data types, assignment statements, and eventually evolving into arithmetic expressions. String variables are not introduced in detail until Chapter 9, but an introduction is given and could be elaborating upon if desired. If time allows, a discussion of how the computer stores data is appropriate. While some of the operations on the primitives are familiar to students, operations like modulus (%) are usually not and require additional explanation. Also, the functionality of the increment and decrement operators requires attention. The issue of type casting is also introduced, which syntactically as well as conceptually can be difficult for students. Some students that have previously learned C may use the old form of type casting (e.g. (int)), but should be encouraged to use the newer form (e.g. static_cast<int>). The section on programming style further introduces the ideas of conventions for naming of programmatic entities and the use and importance of commenting source code. Commenting is a skill that students will need to develop and they should begin commenting their code from the first program that they complete. Indentation is also discussed. However, many development environments actually handle this automatically. 2. Key Points Compiler. The compiler is the program that translates source code into a language that a computer can understand. Students should be exposed to how compiling works in their particular development environment. If using an IDE, it is often instructive to show commandline compiling so students can a sense of a separate program being invoked to translate their code into machine code. This process can seem “magical” when a button is simply pressed in an IDE to compile a program. Syntax and Semantics. When discussing any programming language, we describe both the rules for writing the language, i.e. it [Show More]
