Pointers are a key concept in C programming from "summary" of C Programming Language by Brian W. Kernighan,Dennis Ritchie
Pointers play a central role in C programming. They provide a way to access and manipulate data directly by storing the memory address of another data item. Using pointers gives the programmer a great deal of flexibility and control over how data is stored and accessed in a program. In C, a pointer is a variable that contains the address of another variable. This allows the programmer to create data structures that are more dynamic and efficient than traditional methods. By using pointers, it is possible to pass data between functions without having to make copies of the data, which can be both time-consuming and memory-intensive. Pointers can be used to create complex data structures such as linked lists, trees, and graphs. These data structures are essential for many programming tasks, such as implementing algorithms, managing memory, and organizing data in...
