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).

Note that near and far pointers are outdated by twenty years, but if you still want to know, the answer is two bytes.

How to declare near and far pointers in C?

It used to be a good question 30 years ago. Right know you don't have to know anything about near and far pointers; but if you still use a 16-bit compiler, select 'Large Model' (or 'Huge Model'), and forget 'near' and 'far'


In C you use the concept of pointers whereas there are no pointers used in JAVA why?

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.


Why Near pointers are used for all code and data references in huge memory model for turbo C?

You may have misunderstood something. Choose Huge Model,and forget about near and far. (Honestly, this topic is outdated by twenty years!)


Why pointer is callded jewel of c language?

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.


Function prototype in c?

Yes. Examples can be found in stdio.h

Why are header files not required when using far and near pointers?

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.
