Putting a list inside a list??

[Hiiero]

The program below makes two classes that when calling their generate functions in a .cpp file generates a list of soldiers and then a separate list of skills, I want to combine these 2 lists,that way you can say Soldier 1 has skill 1,4,7 while Soldier 2 has 3,4,5,6,7,8. How would I go about putting these two lists together? In the end I want the user to be able to type in a group of skills he is looking for and then the program make a team consisting of 5 soldiers where each skill the user specified is held by at least two members

class skill
{
      public:
        skill(){}
        skill(int i){x=i;}
        
        ~skill(){}
        bool operator == (skill s){return (x==s.getx());}
        
        void operator = (skill s){x=s.getx();}
      
        void display(){cout<<"a"<<x<<" ";}
        
        void generate1(list<skill>*S);
private:
        int x;

};

class soldier
{
      public:
        soldier(){}
        soldier(int i){x=i;}
        
        ~soldier(){}

        bool operator == (soldier s){return (x==s.getx());}
        
        void operator = (soldier s){x=s.getx();}
      
        void display(){cout<<"S"<<x<<" ";}
        
        void generate2(list<soldier>*S);
private:
        int x;

};

Don't think about it as a list within a list.
Rather, a Soldier has a list of skills.
When you want to know a Soldier's skills, you look at its list.

okay Ive attached a soldier with his list of skills, now Im pretty much stuck on how I would go through the list after the user inputs which skills he is looking for 1-10 and best pick out 5 soldiers to go on a team that meets the requirement of every skill needs to be held by at least two members on the team.

There will be a list<Soldier> inside Skill class. So every instance of the skill class will have the list of soldiers who are having that particular skill. Now for particular skill, Soldiers can be selected.

[thines01]

You would need a function that checks the list for the given criteria.
...and create a NEW list of soldiers with that criteria

//Pseudo

for(int i=0; i < numSoldiers; i++)
{
   Soldier soldier = lstSoldiers[i];

   if(isSuperSoldier(soldier.lstSkills))
   {
      lstSuperSoldiers.Add(soldier);
   }
}

How would I go about writing a display for this class? Because its imputing a file as a parameter,can't for the life of me find how I would get the numbers inside the list to display.

*Edit* Never mind answered my own question on that one

[Hiiero]

Though when I have a list that contains a list in it,how do I pull a single object out of the 2nd list to compare it with something else?

Ex:

class team
{
      public:
        team(){}
        team(int i,list<skill>*Slist){x=i;s = *Slist;}

how would I go about getting a specific value out of team Slist??To get i, I just wrote a getx function that returned the value of x in integer form....

Im trying

-----------------
        int gets(){
              sk=s.begin();
              while(sk!=s.end())
                {
                 a =  sk->getx();
                 sk++;
                 return a;
                }
              }
---------------------

titr=T.begin();
while(x<10)
{
  cout<<titr->gets()<<endl;
  x++;                   
}

but I am only getting the first item in the list to print out,not the rest of the items.

[thines01]

With that code, you have a return statement inside a while loop.
As soon as it gets to the first element, it will return.
Also, I thought you were interested in returning a LIST of skills, not just an integer.

How would I erase the current team object out of the list at this point and time, I tried doing T.erase(titr) but it crashes in the middle of the program. Im trying to do checks and if they are met I am trying to move the current team to a new list and delete the current team from the old list

for(int i = 0;i < v;i++)
                           {
                           skptr = new skill(d[i]);
                           S1.push_back(*skptr);
                           }
                           tptr2 = new team(titr->getx(),&S1);
                           T2.push_back(*tptr2);
                           //T.erase();
                           S1.clear();

To answer your other question about the display:
Just remove the display functions from inside the class.
Return to the user the "data" that needs to be displayed OR return a pointer to the element that is going to be displayed.

That way, you can use this in a CGI or game or other without needing to change the "direction" of the output.
