Accessing data by address. Some data-structures, like lists and trees, are usually implemented using pointers.
a pointer is a derived data type in c. pointers are undoubtedly one of the most distinct and exciting features of c language.it has added power and flexibility to the language. *pointers are more efficient in handling arrays and tables. *pointer can be used to support dynamic memory management. *pointers reduce length and complexity of programs. *increase the execution speed and thus reduce the program execution time. by following character's real power of c lies in proper use of pointers. pointer is called the jewel of c-language.
It doesn't. You must have misunderstood something.
Applications of what? On Windows, for example, you can create Windows-applications in C.
Don't store pointers in files, it makes no sense.
You do not use pointers in Java because the language designers decided to abstract memory management to a higher level in Java than in C. The reason for this is that it is easy to make mistakes using pointers and other lower level memory management techniques. These mistakes can lead to bugs. hard to read code, memory leaks that waste system resources, and security issues. Instead for the most part Java takes care of memory management for the user who can instead specify behavior though the object oriented techniques that are safer and easier to understand. The downside is that the programmers lose some control and flexibility in using memory. Also, programs using Java take a small performance hit in some cases because of the extra work Java has to do to manage memory itself. They are, however in Java they are called references.

Pointers is a very powerful feature that is available in the C programming language but at the same time it is very confusing and many of the issues that arise out of C programs is because of incorrect or inappropriate usage of pointers. Hence the creators of Java language opted to exclude the pointers feature and create Java as a language where the programmer cannot access the native memory area and the memory accessing is left to the system to be taken care of.
Wikipedia can be a starting point.

Let's suppose, you wanted to ask:Why thisis used as a pointer in C++ language? Because it is a pointer to the 'current object'.
yes
Some of them are: 1. char, short, int, long, float, double 2. pointers to these 3. arrays of these 4. arrays of pointers 5. pointers to arrays ...
i don't have any knowledge about your ques. but i guide you to read the "Writing TSR through C" & learn knowledge of FAR & HUGE ponters.by this you can access the adminstrator password using pointers in C.
