新手自学c语言提高效率的方法（Novice self taught C language to improve efficiency） 1.C is the intermediate language. It is the basic structure of practicality and high-level language statements and low-level language combination. C language can be the same place and address of byte as the assembly language to operate, and these three are the most basic unit of computer work. 2.C is the structure of language. Structured language is characterized by a significant separation of code and data, that is all part of the program in addition to the necessary exchange of information and independent of each other. This kind of structure method can make the program clear, easy to use, maintenance and debugging. C language function is provided to the user, these functions can be convenient to call, and with a variety of loops, conditional statements control program flow, so that the program is fully structured. 3.C language function. With a wide variety of data types, and introduces the concept of pointers, make the program more efficient. And the calculation function, logic functions are more powerful, can achieve the purpose of making the game. 4.C language application scope. Suitable for a variety of operating system, such as Windows, DOS, UNIX and so on; also applies to a variety of models. C language to write the hardware required for operation occasions, is better than the other interpretation of high-level language, there are some large-scale application software is written in the C language. The characteristics of the pointer is a major feature of the C language, can be said to be one of the important reasons is better than that of other high-level language C language. Because it is a pointer, can be directly carried out close to the operation of hardware, but the C pointer operation also brings many unsafe factors. C++ do a good improvement in this aspect, while retaining the pointer operation and enhanced security. Java canceled pointer operation, improve the safety, suitable for beg
