Now we'll turn to a concept that is quite important to C programming, but which is unknown in Python, Java, and many other languages: the pointer.1.1. Pointer basicsThe concept of pointer is relatively unique to C: It allows you to have a variable that represents the memory address of ...
Pointer is a very important concept in C language because pointer gives us the concept of address in memory. Everything that is not accessible by the others, pointer can access this very easily with the help of address. Here we will discuss the basic concept of pointer. ...
This is a more advanced concept where a pointer can point to a function, enabling dynamic function calls. This technique is often seen in implementing callback functions. 9. Dynamic Memory Allocation Manual memory management in C is crucial, and pointers are at its heart. Heap vs Stack Memory...
In C programming language, the concept of pointers is the most powerful concept that makes C stand apart from other programming languages. In the part-I of this series we discussed thefundamental concepts around C pointers. In this article, we will try to develop understanding of some of the ...
“Pointers”is the most important concept in C that should be mastered by an embedded systems programmer. “Pointers” are so important because it enables a programmer to work directly with memory of the system. Memory of a system is organized as a sequence of byte sized locations(1 byte =...

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. Double pointers are crucial for advanced C programmin...

In fact, the concept of the null pointer is frequently used as a way of indicating a problem--for instance, some functions left over from C return 0 if they cannot correctly allocate memory (notably, the malloc function). You want to be sure to handle this correctly if you ever use mal...
Let’s reinforce this concept with a brief analogy. Imagine that I am standing in a library and someone walks up to me and says, “Who is Richard the Lionheart?” If I respond by saying, “The king of England from 1189 to 1199,” I am like a normal variable. I am providing the...
