A near pointer is a 16 bit pointer in a 16 bit segmented memory architecture (now obsolete and archaic) that contains only the offset portion of the address of the object.
Wikipedia can be a starting point.
Variables (or constants) that contain addresses.
pro c language to implement linear search 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.
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'.
In C programming, header files are required. It doesn't matter if you are using near pointers, far pointers, both, or neither -- you still need header files. There is no connection between the necessity of header files and the pointers' size.
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 ...
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.
It doesn't. You must have misunderstood something.
Accessing data by address. Some data-structures, like lists and trees, are usually implemented using pointers.
Don't store pointers in files, it makes no sense.
Just forget it, it was a question twenty years ago when we worked in MS-DOS with a 16/20 bit CPU. Near pointers contain 16 bits, far pointers contain 32 bits (but only 1MB (or 1MB+65520 bytes) are really addressible).
