hello, im having troblue getting my linked list to show everything on the list. it only shows the first node, and nothing afterwards.
#include <iostream>
#include <string>
class list
{
private:
struct node
{
std::string name;
std::string phone;
node *next;
}*head, *tail;
public:
list() : head(0), tail(0) {}
~list();
void print() const;
void push_front(std::string, std::string);
bool isempty() const;
};
int main()
{
using namespace std;
do
{
cout << "Enter name: ";
string n;
cin >> n;
cout << "Enter phone number: ";
string p;
cin >> p;
cout << endl;
list ll;
ll.push_front(n, p);
ll.print();
cout << "continue? (y/n)?" << endl;
cout << ">> ";
char yesno;
cin >> yesno;
if(yesno == 'n' || yesno == 'N')
break;
}while(1);
return 0;
}
void list::print() const
{
if(isempty())
{
std::cout << "node is empty..." << std::endl;
return;
}
node *temp = head;
while(temp != 0)
{
std::cout << "name : "<< temp->name << std::endl;
std::cout << "phone number : " << temp->phone << std::endl;
std::cout << std::endl;
temp = temp->next;
}
std::cout << "\n\n";
}
void list::push_front(std::string n, std::string p)
{
node *temp = new node;
temp->name = n;
temp->phone = p;
temp->next = 0;
if(isempty())
head = tail = temp;
else
{
temp->next = head;
head = temp;
}
}
bool list::isempty() const
{
return head == 0;
}
list::~list()
{
node *temp = head;
node *tmp;
while(temp != 0)
{
tmp = temp;
temp = temp->next;
delete tmp;
}
}
