In this tutorial, you'll learn about pointers; what pointers are, how do you use them and the common mistakes you might face when working with them with the help of examples.
These are three declarations of pointers. Each one is intended to point to a different data type, but, in fact, all of them are pointers andall of them are likely going to occupy the same amount of space in memory(the size in memory of a pointer depends on the platform where the prog...
In this tutorial, you'll learn about the relationship between arrays and pointers in C programming. You will also learn to access array elements using pointers with the help of examples.
Java, as a language, is built on a robust security model, which explicitly prohibits pointer arithmetic for the same compelling reasons. Allowing pointer arithmetic in Java would present a challenge for the Virtual Machine to guarantee the safety of code without incurring substantial overhead from ...
This way of working with arrays might seem a bit excessive. Especially with simple arrays like in the examples above. However, for large arrays, it can be much more efficient to access and manipulate arrays with pointers. It is also considered faster and easier to accesstwo-dimensional arrays...

Read on for concrete examples. Example Uses of Function PointersFunctions as Arguments to Other Functions If you were to write a sort routine, you might want to allow the function's caller to choose the order in which the data is sorted; some programmers might need to sort the data in ...
Pointers to Pointers It is possible and often useful to create pointers to pointers. This technique is sometimes called ahandle, and is useful in certain situations where the operating system wants to be able to move blocks of memory on the heap around at its discretion. The following example...
