dynamic allocation of 2d array

[akki_freak]

Hi guys...

consider this...

int a[10][3];

will give us a two dimensional array.

Now can we do the same thing using malloc at run
time?? Think.... :D

In C:

int **a, x;

a = malloc(sizeof(int *) * 10);
for(x = 0; x < 10; x ++) {
    a[x] = malloc(sizeof(int) * 3);
}

/* ... */

for(x = 0; x < 10; x ++) {
    free(a[x]);
}
free(a);

You can even enlarge the array, or shrink it or whatever, using realloc().
