 Programming in C Language: Pointers Define Pointer. A pointer is a variable that stores a memory address. Like all other variables, it also has a name, has to be declared, and occupies some spaces in the memory.  Why Pointer is called Pointer?  It is called a pointer because it points to a particular location in memory by sorting the address of that location. Pointer General Syntax of Declaration data-type * Pointername; Here, Pointername = Name of pointer variable Astric * preceding this name informs the compiler that the variable is declared as a pointer.  Data type = Base type of pointer. For example:          int * iptr;          float * fptr; here iptr is a pointer that should point to a variable of type int. Pointers are also variables so, the compiler will reserve space for t hem and they will also have some address. All pointers irrespective of their base type will occupy the same space in memory since all of...
