As such, it can easily be flung off to a function in C programming. Even more thrilling, a pointer can wander back from a function as a return value. They have data type just like variables, for example an integer type pointer can hold the address of an integer variable and an character type pointer can hold the address of char variable. In your example int *ptr,*ptr1; both ptr and ptr1 have type "pointer to int", which can only point to an int, not a pointer.
