It is accessing data by address.
It is a pointer which is pointing to present object with which the memberfunction is called in c++ language.
Pointer in C is Memory Reference. It stores memory address of any variable, constant, function or something you later use in your programming. Pointer basically used to ease the referencing of variables and others or in polymorphism and inheritance.
An address in C or C++ is the location in memory of an object or function. An address is the contents of a pointer, as opposed to the contents of the memory location pointed to by the pointer.
yes, ds cs es ss are pointers available in c which is used to refer memory segments

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.
System Programming
You do not. A pointer is an opaque value that you do not care what its internal bit value is. You only care that it points to a region of memory that you can do something with. You can scan that region of memory, but not the pointer itself.
if (*&a > *&b) *&max = *&a; else *&max = *&b;
with the help of pointers we able to store the memory location of any variable. In c the pointer variable is use to store the memory location of any variable. The pointer variable is define as a simple variable but in pointer variable use a special "*" character at the left most side of name of pointer variable. If any variable name have * it means it is a pointer variable it hold the memory location of variable.
