The 1th chapter is the introduction, the content is relatively simple, you can read it quickly, and appropriate to do some exercises, and so on after the end of the chapter and then back to do the remaining exercises. Here are a few important points of knowledge:1.1-1.3(1) "P2" C language programs are composed of functions and variables , the function contains a number of statements statement to perform some operations, variables are used to store the operation of the value that needs to be used
