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.
A bit of poetry, forget it. What is true: pointers are very important in C Programming.

Explain pointer to function with example c language?
It isn't a question, sorry.
Why use pointer in c language with file handling?
Don't store pointers in files, it makes no sense.
Why void is used in c language?
void as function return-type means no return value void as function parameter means no parameter void * as pointer type means generic pointer
What is 'this' in c?
There is no 'this' in C. C is not an object-oriented language. C++, however, is object-oriented. The 'this' pointer is used by non-static member functions to determine which instance of a class the function should operate upon.
Is type checking on pointer variables stronger in assembly language or in c plus plus?
C++ imposes far greater restrictions on pointer typing than assembly language. There is only a single type of pointer in assembly, which is only "typed" in any sense when dereferenced, and even then only by size. C++ pointer typing takes into account not only the size of the type of the referent, but a number of other factors, such as its relationship to other types in the class hierarchy. The only way to disable these safety checks is to explicitly break the type system using reinterpret_cast.
Why does is used as a pointers in 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'.
What is far pointer in c language?
its pointer created for high safety that cant be find by anyone.
What is 'this pointer' in regards to computer programming?
It is a pointer which is pointing to present object with which the memberfunction is called in c++ language.
When would you use a pointer and a reference variable?
pointer: to access data by address reference: there is no reference in C language
Is 'a' equals ''a'' in c language?
No, the first is a number (0x91), the second is a pointer.
Explain pointer to function with example c language?
It isn't a question, sorry.
Why does array index start with zero in C language?
Because of pointers and that all arrays are really pointers. A pointer something like *pointer can also be written as pointer[0] and *(pointer + 1) can also be written as pointer[1]
Why use pointer in c language with file handling?
Don't store pointers in files, it makes no sense.
Why pointer can't be added in computer language C?
You can add a point in C/C++. The legal operations on a pointer are that you can 1.) add a constant, 2.) subtract a constant, and 3.) subtract two pointers that refer to the same array. Anything else is meaningless.
What is the size of the pointer in c language?
Platform-dependent, printf ("%d\n", (int)sizeof (void *))will tell you.
Do you have pointer concept in c plus plus language?
Yes. All string variables are pointers as are other arrays.
Why void is used in c language?
void as function return-type means no return value void as function parameter means no parameter void * as pointer type means generic pointer
