Programming in C: Unit III (b): Pointers
Pointers to Pointers
with Example C Program
In C language you are also allowed to use pointers that point to pointers. The pointers in turn, point to data (or even to other pointers). To declare pointers to pointers, just add an asterisk (*) for each level of reference.
POINTERS
TO POINTERS
In
C language you are also allowed to use pointers that point to pointers. The
pointers in turn, point to data (or even to other pointers). To declare
pointers to pointers, just add an asterisk (*) for each level of reference. For
example, if we have:
int x = 10
int *px; //pointer to an integer
int **ppx; // pointer to a pointer
to an integer
px = &x;
ppx = &px;
Assume
that the memory location of these variables is as shown in Figure 7.9.
Now
if we write,
printf("\n %d", **ppx);
then
it will print 10, the value of x.
