Do you know what's Pointer? In this post you will have a theory about the pointer, it's notation, address, referencing and dereferencing. you understand that if we know the address we can find the value so in spite of value just play with an address that what pointers do. A pointer points to a memory address
Today I’m going to take you on a ride of pointers with the help of different topics. We all know that we’re very afraid of pointers since we first read it. Today I’m going to try to let you explain the uneasy POINTERS, to make you learn Pointers. What are Pointers? First of all, starting with the explanation where these have come from i.e. Dynamic Data Structures in which many things like pointers, linked list, stack, queues and different things …
The students of computer science have a nightmare about the pointer, It's difficult to learn pointer but it's more difficult when we want to implement it. We normally face 3 types of problem What do u mean by &a and *a or **&a if *a is used in method overloading then when it is not used, or when it is useful Find the output of this program if the statements are like
No matter how big the array is, the user could still have more input. or If the user doesn't have that much input, you have wasted memory.To overcome this problem we use runtime memory allocation. In this article, we will learn about dynamic allocation and dynamic data structures.
