6.7. Putting It All Together
A Character List Class
“Friend Classes” on page 246 introduces a List class that stores character strings. Here's another version of List with overloaded member functions.
Listing 6.4. List objects with remove()
// plist2.C - remove and print List of char * strings
#include <iostream.h>
#include "List2.h"
const int max = 3;
int main()
{
static const char *brothers[] = { "groucho","chico","harpo" };
List L1;
for (int i = 0; i < max; i++)
L1.append(brothers[i]);
cout << "L1 has " << L1.length() << " strings" << endl;
L1.print();
L1.remove(L1.getEnd()); // remove last entry
L1.remove("chico"); // find and remove "chico"
L1.print(); // display modified List
return 0;
}
$ plist2 L1 has 3 strings groucho chico harpo groucho ... |
