What are pointers in C language?

Hi Imran, Hope you are doing good. Are you looking for short answer or long answer? :) Pointers in C are variables that store memory addresses. They point to the location of another variable, allowing direct access to the value or data stored at that memory address. Pointers are a powerful feature in C, enabling dynamic memory allocation, efficient array manipulation, and facilitating the implementation of data structures. Hope this answers your questions. If you need further clarification let me know Regards Raj read less

In the C programming language, a pointer is a variable that stores the memory address of another variable. Instead of holding the actual value of the data, a pointer contains the location (address) in memory where the data is stored. Pointers play a crucial role in C, providing a mechanism for direct memory manipulation and allowing efficient implementation of data structures and dynamic memory allocation. They enable more efficient use of resources and are essential for tasks such as passing parameters by reference, dynamic memory allocation, and building complex data structures like linked lists and trees. One of the fundamental operations with pointers is dereferencing, which involves accessing the value stored at the memory address pointed to by the pointer. The asterisk (*) symbol is used to declare a pointer and to dereference it. Pointers are powerful but also require careful handling to avoid issues such as memory leaks, dangling pointers, and undefined behavior. Despite their complexity, understanding and mastering pointers is considered a crucial skill in C programming, allowing developers to create efficient and flexible code by directly managing memory and manipulating data at a low level. read less
