A pointer is a variable that contains the memory address of another variable, function, or object, called the pointee.
Creating Pointers
Pointers are declared as any other variable, except that an asterisk (*)
is placed between the data type and the pointer’s name. The data type used determines what type of memory it will point to. More than one pointer can be created in the same statement using the comma operator. The asterisk must then be placed before each identifier and not after the type.
int* p; // pointer to an integer
int *q; // alternative syntax
int *a, *b, *c; // multiple pointers
