Pointer is a crucial concept in C language,which has a wide range of applications and is extremely flexible.This paper explores the basic concepts and practical applications of pointers in C language.Firstly,this paper introduces the definition,basic operations,and role of pointers in memory management.Then,the application of pointers in function parameter passing,dynamic memory allocation,and data structures such as linked lists,stacks,and queues was discussed in detail.Through case analysis,it demonstrates how pointers can improve the efficiency and flexibility of programs,and overcome some limitations in traditional array operations.Especially in the implementation of dynamic data management and complex data structures,the application of pointers significantly improves the performance and scalability of programs.Finally,this paper summarizes common problems and their solutions in pointer usage,in order to help developers better understand and utilize this powerful tool.
