Question

Somehting about how I initialize my private class memebers. The warning messages do not makes sense…I tried to see if they were concatenated..but they do’t appear to be..this is what Eclipse is saying. Sorry I can’t format it much better.

Here are the compiler message:

Description                               Resource  Path    Location    Type
'sl_list<int>::node_1* sl_list<int>::head'  test_a      line 13 C/C++ Problem
when initialized here                       test_a      line 18 C/C++ Problem
'sl_list<int>::count' will be initialized   test_a      line 14 C/C++ Problem

Relevant Code – call to linked_list

#include "c_include_list.cpp"
#include "c_linked_list.cpp"

using namespace std;

int main() {
    cout << "sl_list" << endl;
    sl_list<int> sl_list_object;
}

Relevant Code – linked_list implmentation

template <class T1> class sl_list
  {
  private:

      class node_1 
      {
      public:     
        T1 data; 
        node_1 *next;
        node_1(T1 data, node_1 *next = NULL) : data(data), next(next) {}        
      };

    node_1 *head;  // line 13
      int count; // line 14

  public:

    sl_list() : count(0), head(NULL){} // line 18

The answer is pretty simple: Initialize members in the order of declaration.

sl_list() : head(NULL), count(0){}

By default, this is only a warning, so Eclipse probably gave the -Wall and -Werror flags to the compiler.
