I need to make a linked list with classes. Each list will store two values: a URI and IP. After doing all the adding, I need to be able count the
total number of items in the linked list. I have tried the following code but it doesn't compile. Any suggestions please?
#include <iostream>
#include <cstdlib>
#include <string>
using namespace std;
class ip_uri_store {
protected:
string ip;
string uri;
ip_uri_store *next;
public:
ip_uri_store(string huri, string hip);
void additem(string auri, string aip);
void deleteitem(string duri);
void findbyuri(string furi);
void findbyip(string fip);
int totalitems();
};
ip_uri_store *head = NULL;
ip_uri_store *curr = NULL;
void ip_uri_store::additem(string auri, string aip)
{
curr = head;
while (curr->next != NULL) {
curr = curr->next;
}
curr->uri = auri;
curr->next = new ip_uri_store;
curr->ip = aip;
curr->next = new ip_uri_store;
curr = curr->next;
curr = head;
}
int ip_uri_store::totalitems()
{
int i = 0;
curr = head;
while (curr->next != NULL) {
i += 1;
curr = curr->next;
}
return i;
}
int main(int argc, char *argv[])
{
if (argc == 1) {
cout << "123456,
[email protected], Gordon Brown" << endl;
return (0);
}
head = new ip_uri_store;
curr = head;
int i;
for (i = 1; i < argc; i++) {
if (argv[i][0] == 'A') //add item
{
ip_uri_store.additem(argv[i + 1], argv[i + 2]);
i += 2;
}
else if (argv[i][0] == 'N') //print
total tiems
{
cout << ip_uri_store.totalitems() << endl;
}
else {
cout << "command error\n";
return 0;
}
}
return (0);
}
