How can I dynamically allocate arrays?
The equivalence between arrays and pointers allows a pointer to malloc'ed memory
to simulate an array quite effectively. After executing
#include <stdlib.h>
int *dynarray;
dynarray = malloc(10 * sizeof(int));
(and if the call to malloc succeeds), you can reference dynarray[i] (for i from
0 to 9) almost as if dynarray were a conventional, statically-allocated array (int
a[10]). The only difference is that sizeof will not give the size of the ``array''
