Managed pointers in C# explained A managed pointer differs from a type-safe pointer in being able to point to other locations of an object, i.e., not just the beginning of the object. Like an object reference, a managed pointer can point to objects stored in the managed heap. The differ...
Note:-In fact we can actually declare a pointer variable without any data type using the keyword void. It is known as a void pointer. The topic of void pointer has to be explained separately – so I will explain it in my next post. Assigning address to a pointer variable To make use ...

C Pointer to Pointer, Pointer to Functions, Array of Pointers Explained with Examples 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...
In C and C++ programming, pointers are very powerful. As we explained in C pointers example article, pointers are variables that hold address of another variable so that we can do various operations on that variable. Sometimes a programmer can’t imagine
That’s not a correct term, but I have considered it appropriate to be used in this case. In all the above topics, I explained only the cases in which we are assigning to the pointer the address of an already defined variable. But what can we do with pointers when we do not assign...
This is explained in the figure below. Now,num2also points tonumbecause it contains the memory address ofnum. Thus, pointers are a helpful tool in programming and provide us with efficient memory and time management during programming.
Pointers to void is explained in Pointer to void. To keep our examples simple, we will use the %p specifier and not cast the address to a pointer to void. Virtual memory and pointers To further complicate displaying addresses, the pointer addresses displayed on a virtual operating system are ...
Note:A void pointer cannot be directly dereferenced because it is not pointing at a specific type. (Reference and dereference is explained further down.) Before you can use a pointer in for instance a cout statement, you have to initialize the pointer. ...
The fact that you correctly read the original value in the second case (when you don't call delete) is because the original object has not been changed (you change a new one in testFinction1 and the pointer to it in main is the same (as explained above) and the object is still ali...
