Personal I have a question of where and how should I change to this function to print circular list is correct.
Below is a print function from a linked list:
void imprime_lista(tipo_lista* p)
{
while (p != NULL)
{
printf("%d\n", p->info);
p = p -> prox;
}
printf("\n");
}
It only changes that the repeat loop stop criterion will be when it reaches the first loop. It is also necessary to change while to do , because the list already starts in the first element and with while will not print anything.
void imprime_lista(tipo_lista* p)
{
if(p==NULL)
return;
tipo_lista* primeiro = p;
do
{
printf("%d\n", p->info);
p = p -> prox;
}while(p != primeiro);
printf("\n");
}
