Pointers are the most important topic in the C programming language. In memory allocation, each block where any data is stored is capable of storing 1 byte of information. The pointer is the variable that enables us to store the address of the variables to which we want to point. The valu...
Except a few, most of the programs in C may be written with or without pointers. Then the question arises “Why use pointers if you can do without them?” Pointers are considered to be useful tools in programming because of the following reasons: (i) Pointers make the programs simple and...
Pointers lay the foundation of C programming, offering direct memory access and manipulation capabilities that are both powerful and complex. As we delve deeper into pointers, we encounter double pointers, an extension of the basic pointer concept. Do
far, and huge pointers. In older Intel processors, the registers were 16-bit while the address bus was 20-bit wide. This mismatch meant registers couldn’t hold complete addresses. To manage this, memory was split into 64 kB segments. Concepts like near, far, and huge pointers in C were...

Function Pointers in C and C++By Alex Allain A function pointer is a variable that stores the address of a function that can later be called through that function pointer. This is useful because functions encapsulate behavior. For instance, every time you need a particular behavior such as ...
