Does anyone know where could i find an implementation of a SET, or a
DICTIONARY out there? I am working on a project and would like to use these as an
example.

Thank you.

hi,everybody,
sorry to re-post this question because I found my question was cut in last time
----------------------------------------------------------------------------




I am a new comer to use "template",I have a strange case in the following code:

extern "C" {
#include <string.h>
#include <stdio.h>
#include <ctype.h>
}

#include<iostream.h>
#include<strstream.h>
#include<stream.h>

template <class T>
class D {
 char tname[10];
 T* t;
public:
 void insert(){
  t=new T;
  strcpy(tname,"T1");
  t->insert("CT1");
 //printf("strange staff happens\n");
/* This stmt made different output i,if I comment this stmt the output is
wrong (see case 1),otherwise it output what I need.(case 2) Why?
case1 (wrong answer)
 tname::T1
 contain:CT1
 contain:

case2 (correct answer)
 tname::T1
 contain:CT1
        contain:CT2
        strastaff happens */

  (t+1)->insert("CT2");
  }
 void output(){
  cout <<"tname::"<<tname<<"\n";
  t->output();
  (t+1)->output();
  }
};

class C {
 char cname[10];
 int cid;
  public:
 C(){
  strcpy(cname,"");
 }
 void insert(char name[10]){
  strcpy(cname,name);
  cid=2;
  }
 void output(){
  cout <<"contain:"<<cname<<"\n";
  }
};

int main (int argc,char* argv[])
{
 C c;
 D<C> d;
 d.insert();
 d.output();
}

Thank you advance
