Implementarea stivei cu memorie dinamicǎ (cont.)<br />

Variantǎ cu <strong>de</strong>alocarea memoriei in pop() (simetric cu push):<br />

elem_t pop(stack *s) {<br />

elem_t e = (s->sp!=s->base) ? *--s->sp : 0;<br />

if (s->lim - s->sp == 64) { /* limitǎ pt. <strong>de</strong>alocare */<br />

p = realloc(s->base, (s->sp-s->base)*sizeof(elem_t));<br />

s->lim = s->sp += p - s->base; s->base = p;<br />

}<br />

return e;<br />
