Since arrays are just contiguous areas of bytes, you can allocate your own arrays in the

heap using malloc(). The following code allocates two arrays of 1000 ints-- one in the

stack the usual "local" way, and one in the heap using malloc(). Other than the different

allocations, the two are syntactically similar in use.

{

int a[1000];

int *b;

b = (int*) malloc( sizeof(int) * 1000);

assert(b != NULL);      // check that the allocation succeeded

a[123] = 13;      // Just use good ol' [] to access elements b[123] = 13;               // in both arrays.

free(b);

}

Although both arrays can be accessed with [ ], the rules for their maintenance are very

different....
