Accessing Run-Time Storage

• If we allocate a cell by defining a variable, we can access it by using the variable's name or by dereferencing a pointer to the cell.

• If we allocate cells at run time, we can access it only through a pointer.

int num, *p1, *p2;

num = 10; /* access by naming */

p1 = #

*p1 = 1000; /* dereferencing */

p2 = malloc(sizeof(int));

*p2 = 99999; /* only way is dereferencing */
