A pointer is a programming tool that allows a value to be referenced. All data is allocated in memory and has a certain address attached to them. When you use a pointer, you are taking a value from an address called the reference. The original data is called the reference, and taking that value using a pointer is called dereferencing.
Example using Objective-C:
int anInt = 42; (anInt is stored in memory with the value of 42)
int *anIntPointer; (this is new datatype that wants to point to a certain address)
*anIntPointer = &anInt; (you are taking the pointer and dereferencing it to anInt. anytime you have a pointer [in this case denoted with an asterisk "*"], the reference will be noted with an ampersand "&")
Now there are also pointers to objects and structs that use an entirely different method, but same idea, the pointer grabs a referenced data value. This is especially valuable for referencing structures without having to reference every single member variable.

Pointers in C are generally the thing that gives learners the most trouble. When C code is not written correctly with respect to pointer use, the resulting bugs can often be very difficult to find and correct. On the other hand, pointers are absolutely necessary in some cases.The designers of Java wanted to make programming easier and hence avoided adding pointers to the language. Java does have object references which accomplish much of what pointers accomplish albeit in a safer way.
All programming languages implement pointers, but not all languages allow low-level access to memory through a raw pointer. Java, for instance, uses resource handles and smart pointers rather than raw pointers, however the actual allocation of memory is handled by the Java virtual machine (JVM) so there is no need for low-level raw pointers.
An array of pointers is a contiguous block of memory that contains pointers to other memory locations. They essentially allow non-contiguous memory locations to be treated as if they were an actual array.
It would be better to say, 'I am forwarding this mail, for your information.', or 'We are forwarding this mail for your information.'
When forwarding an email, you should briefly explain why you are forwarding it and provide any necessary context for the recipient.
They are pointers without type
IP forwarding enables one workstation to sit on two LANs and to act as a gateway forwarding IP packets from one LAN to another. IP forwarding is also referred to as 'bridging' networks.

POINTERS ARE USED TO STORE ADDRESS
Java does not support pointers.
Call forwarding is a popular service that allows for calls to be forwarded to your phone. The code to set up call forwarding is usually *72.

Web forwarding is when you have a website and you want to forward stuff to another website. The advantages of web forwarding is that it makes things a lot easier to do.
