摘　　要：指针在C语言程序设计中占有重要地位,指针变量的灵活性是C语言的主要特色之一。指针变量能够方便表示各种复合数据类型,可以使用数组和字符串,同时也可以处理内存地址。文章首先论述了指针和地址的关系,以及指针的定义;其次,根据指针的实质化繁为简,总结了3种不同的指针赋值方式;再次,给出了常用的指针运算和注意事项;最后,辅助以举例和练习。指针变量的灵活性也带给程序一定的危险性,因此能否正确理解和使用指针是是否掌握C语言的一个标志。The pointer occupies an important position in programming in C language,and the flexibility of pointer variables is one of the main features of C language.Pointer variables can easily represent a variety of composite data types,can use arrays and strings,and can also handle memory addresses.This article firstly discusses the relation between pointers and addresses and the definition of the pointer,then simplifies the complex according to the essence of pointer and summarizes three different pointer assignment methods,gives commonly used pointer operations and matters needing attention again,and finally gives auxiliary examples and exercises.The flexibility of pointer variables also brings some risks to the program,so whether you can understand and use pointers correctly is a sign of mastery of C language.
