Pointers On C brings the power of pointers to your C programs. Designed for professionals and advanced students, Pointers on C provides a comprehensive resource for those needing in-depth coverage of the C programming language. An extensive explanation of pointer basics and a thorough exploration of their advanced features allows programmers to incorporate the power of pointers into their C programs. Complete coverage, detailed explanations of C programming idioms, and thorough discussion of advanced topics makes Pointers on C a valuable tutorial and reference for students and professionals alike. Features and Benefits Provides complete background information needed for a thorough understanding of C. Covers pointers thoroughly, including syntax, techniques for their effective use and common programming idioms in which they appear. Compares different methods for implementing common abstract data structures. Offers an easy, conversant writing style to clearly explain difficult topics, and contains numerous illustrations and diagrams to help visualize complex concepts. Includes Programming Tips, discussing efficiency, portability, and software engineering issues, and warns of common pitfalls using Caution! Sections. Describes every function on the standard C library. For those who need an up-to-date ANSI overview of the C programming language, this book would be an excellent introduction. Pointers are usually a stumbling block for those programming C initially, but the author does an excellent job of detailing the use of pointers in this book. The use of pointers dominates the entire book, and after studying it, readers will have a thorough, practical knowledge of how to take advantage of the performance power of C language, due mostly to its use of pointers. For those programming in a commercial/business environment, where coding practices are strictly enforced, this book would be a good desk reference, as the author includes discussion of sound programming practices throughout the book. The book would also serve well those involved in teaching C in the classroom, as it contains many exercises, ranging from very easy to highly advanced. And for those readers frequently facing legacy code in C, such as scientific programmers, the author cites the differences between the older "Kernighan-Ritchie" C, and the more modern ANSI C, the latter being used in the book. These differences are indicated in the margin of the book, and are of an enormous help for those who must take older code and get it to run on more up-to-date compilers. The author also endeavors to organize the C code for those who are going on to study C++ and the accompanying object-oriented approach to programming. In addition, he emphasizes how to write C code so as to make it more portable. For those writing commercial applications in C that must be used on different platforms, this is a very important issue of course. Particularly well-written is the author's discussion on the storage class of a variable, noting, for those such as I who are pre-disposed to using recursion, that the formal parameters to a function cannot be static if recursion is to be supported. The book is full of examples such as this that give readers insight on the workings of C that fit their particular programming style. He does discuss `goto' statements in relation to function scope and in C statement structures, but, thankfully, recommends such statements never be used. He gives an interesting counterexample to those who say that goto statements must be used to break out of nested loops. Also, the author discusses the difference between L- and R-values, and this is not usually included in beginning books on C. Dynamic memory allocation has been at times a somewhat painful aspect of programming in C, but the author shows how to do straightforwardly in the book. Having a book like this that is predominantly about pointers is quite a blessing for those who are inexperienced with them or for more experienced programmers who are still uncomfortable with their use. It is not uncommon these days to have to write programs in one's professional work that involve triple pointers or even quadruple pointers. In addition, for embedded systems programming, the use of pointer arithmetic is almost mandatory. This also is true for writing applications in cryptography using C. The author does pay careful attention to pointer arithmetic in the book. The performance pay-off for using pointers is undeniable, and so a thorough knowledge of their use and pit-falls is of upmost importance for those C programmers who are involved in writing performance-sensitive applications. The author discusses in detail what can happen when pointers are misused and gives many examples of what to avoid and good hints for the proper use of pointers. He recommends against the use of the `null' pointer in array searching, and recommends a strategy for circumventing them. Some very helpful diagrams are given for explaining pointer expressions. In addition, the author gives helpful hints on when to use pointers and not subscripts when manipulating arrays in C. The performance issues involved in this are extremely important in scientific programming using C. The author gives a very interesting example of the differences in performance using pointers involving a program to copy the contents of one array into another. Arrays of pointers, useful in data mining applications, are also given ample treatment in this book, and the author addresses the issue of when to use a matrix instead of an array of pointers. The author also gives an effective presentation of functions in C, particularly the construction of recursive functions, and he employs some useful diagrams to illustrate how the variables in a recursive function call change on the stack. The performance hit experienced by using recursion versus iterative loops is discussed in a standard way via the Fibonacci series. Those readers raised in the functional programming paradigm will want to pay notice these performance issues when using C to do recursion. Along the same lines, the author shows how to implement functions with variable argument lists in C. This is another topic that is frequently passed over in beginning books on C. The author's treatment of data structures in C is also very nicely done, and he includes again a topic not usually treated in beginning books on C, namely the concept of a self-referential data structure. These are very important in applications in artificial intelligence, and the author shows how to implement them in C using a data structure that points to itself. This leads to a discussion of incomplete declarations. Very helpful diagrams are used again to discuss how to access members of data structures and how to point to data structures. Bit fields, so often used in embedded system applications, are also given a detailed treatment.

百度地图的网页，调用百度地图api的javaScript，这里得创建自己的工单，申请自己的密钥key(申请的是浏览器端)，通过输入经度纬度、线宽、线的颜色、线的透明度，实现百度地图的标点，折线，画图（注意：这里标点输入的直接是经度纬度中间用逗号隔开，例如【116.399, 39.910】，而折线和图的形成输入的也是经度纬度，每个经度纬度中间用分号隔开，例如【 116.399, 39.910;116.405, 39.920;116.425, 39.900】），页面里面也实现了隐藏poi文字、还有覆盖物清除、进行测距（在地图上随意标俩个点就可以获得之间的直线距离）、随意放大和缩小地图的按键也可通过鼠标。最后一个路径规划的输入框，是输入一个json(例如百度地图两点之间百度地图的路线规划)，这个输入的json是怎么样可以在baidu.js文件中进行修改一下参数设置就可以。这个是我们公司的路径规划路线返回的json字符串，然后传入到百度地图，与百度地图的路径规划看看是不是差距很大。
