struct node {
int data;
struct node* next;
};
int main (int argc, char * const argv[]) {
struct node *start_ptr = NULL;
struct node *newpointer = NULL;
newpointer->next = NULL;
start_ptr->next = newpointer;
return 0;
}
struct node {
int data;
struct node* next;
};
int main (int argc, char * const argv[]) {
node *start_ptr = new node;
node *newpointer = new node;
newpointer->next = NULL;
start_ptr->next = newpointer;
return 0;
}
newpointer is NULL.. so you're trying to dereference a NULL pointer. You need to allocate memory for the node, for example with new or malloc. Is this supposed to be C or C++?
Ok, well I actually got it to work by changing it to the following:
struct node {
int data;
struct node* next;
};
int main (int argc, char * const argv[]) {
node *start_ptr = new node;
node *newpointer = new node;
newpointer->next = NULL;
start_ptr->next = newpointer;
return 0;
}
But, I am confused on why the new node is need and and why I can't just use NULL?
