Functions In C++ and most modern programming languages, we may put statements into functions to be invoked in the future. Also known as procedures in some languages. Why functions We need modules instead of a huge main function. Easier to divide the works: modularization. Easier to debug: mantenance. Easier to maintain consistency. We need something that can be used repeatedly. Enhance resuability Structure of functions In C++, a function is composed of a header and body. A header for declaration:

Introduction Arrays A collection of variables of the same type. An array variable is of an array type, a non-basic data type There are many non-basic data types: Arrays Pointers. Self-defined types. … Basic data types In C++, each variable must be have its data type It tells the system how to allocate memory spaces and how to interpret those 0s and 1s stored there. It will also determine how operations are performed on the variable. Basic (or build-iun or

Preprocessors Preprocessor commands, which begins with #, performs some actions before the complier does the translation. The include command is to include a header file: Files containing definitions of common variables and functions. Written to be included by other programs. #include <iostream>: Before the compilation, the complier looks for the iostream header file and copy the codes therein to replace this line. We may define our own variables and functions into self-defined header files and include them by ourselves: #include "myHeader" Use double quotation marks instead of angle brackets.

A programming language may be a machine language, and assembly language, or a high-level language (or something else) Machine and assembly languages: Control the hardware directly, but hard to read and program. High-level languages: Easy to read and program, but need a “translator”.
