Thread: Advantages of pointer

I am new in programming word. I am learning C programming language. I have little bit knowledge of C. but I am not able to understand pointer concept in C. I want to know advantages of pointer. Is it any special use of pointers? If you know any advantage of using 'Pointer', then please let me know that.

The basic advantages of using pointer are that,

• It allows the use of dynamic memory allocation.

• A pointer is a variable containing the address of a different variable of a type.

• The concept of pointer is often scared because this is a technical programming very powerful for defining dynamic structures that is to say that advances over time.

As in C, the C + + permits to use pointers to operate data, but it also introduces the concept of reference handy to permit editing of data passed in a function. A pointer is a variable that should be defined by specifying the type of variable pointed. With the symbol '*' the compiler knows it is a variable of type pointer and not an common variable, again, known that you specify (necessary) the variable type, the compiler knows how many blocks after block located at address.
