It may be noted that as a C programmer, we do not need to know the actual address stored in a pointer variable in most situations. Moreover, the pointer variable may physically be present anywhere in main memory, either before the variable it points to or after it. Hence, an arrow is ...
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...

C Pointers: Near, Far, and Huge - Explore the concepts of near, far, and huge pointers in C programming. Understand their differences, use cases, and memory management implications.
Pointers in JavaScript? An underscore is used to denote a pointer in the following example: Solution 4 is presented, which involves referring to 'x' from the window object. The question being asked is whether pointers are available in JavaScript. The asker notes that in C++, pointers are ...
Final notes Iterators behave like pointers: can't I just use them? Our custom container is a wrapper around an old-school array, which can be navigated with pointer arithmetic. Indeed we could get rid of the whole Iterator class and just return a pointer to the first and last array elemen...

In this step-by-step tutorial, you'll get a clearer understanding of Python's object model and learn why pointers don't really exist in Python. You'll also cover ways to simulate pointers in Python without the memory-management nightmare.
Just like every variable in a program has an address, every function in a program too has an address. The name of the function can be used to obtain the address of a function. This address can be stored in a special type of variable which are pointers to
