Segmentation Fault and linked lists
Hello, this is my first submission at this forum, hope you'll help ; )
I wrote this program to see if I knew how to manipulate linked lists:
Code:
#include <stdio.h>
#include <stdlib.h>
typedef struct List {
int number;
struct Lista *next;
} list;
main () {
int p, i;
lista *begin, *new;
inicio->prox = NULL;
scanf("%d", &p);
new = ( list * ) malloc( sizeof( list ) );
new->next = NULL;
begin = new;
for ( i = 0; i < p; i++ ) {
new = ( list * ) malloc( sizeof( lista ) );
new->number = i;
new->next = begin;
begin = new;
}
while ( new->next != NULL ) {
printf("%d\n", (*new).number);
new = new->next;
}
for ( i = 0; i < p; i++ ) {
new = begin;
begin = begin->next;
free(new);
}
return 0;
}
It simply reads an integer 'n' from the keyboard and then generates a linked list with 'n' elements, with each element receiving, progressively, a number (from 0 to 'n') to "number". Then it prints each "number" and frees the allocated memory.
When I try to compile it with gcc (I'm at a Fedora OS), it returns something like "Segmentation fault (kernel image recorded)" ("Falha de segmentacao (imagem do nucleo gravada).
Can you tell me what's wrong?
Thanks a lot!
