    Need a little help with lists in a Class

    Ok, I just need a little help. I remember trying to make a list for another Class a few months back for a game I was making for a school assignment, and the list didn't want to initialize. I can't test this yet, as my program isn't done yet, but I just wanted to see if my code so far was correct.

    The first part(cut down for clarity):

    Code:
    private:
    
      int maxhp;
      int fightermaxhplist[50] = { 35, 63, 91, 120, 149, 178, 207, 237, 267, 297, 327, 333, 364, 395, 401, 433, 465, 472, 504, 537, 545, 578, 611, 620, 629, 663, 672, 682, 717, 727, 737, 773, 784, 795, 831, 843, 855, 892, 904, 917, 955, 968, 981, 1020, 1034, 1048, 1087, 1102, 1117, 1157};
    The second part:

    Code:
    int charstats::calculatemaxhp()
      {
        if((charclass==1) || (charclass ==7))
        {
          maxhp = fightermaxhplist[level-1];
        }
    Will that work, or will I have to initialize the list some other way? I'd like to keep the list in the class if that's possible, though I could work it into the main program if I had to.

    You cannot init data directly in the class, that's what the constructor is for.

    Well, that kinda sucks. Thanks for the reply, though. Guess I'll have to rework my class, and put that into my main program.

    You can use a pointer as long as you remember to free up the memory when the object is destroyed.
    Code:
    class Fighter
    {
    public:
    	Fighter();
    	~Fighter() { delete [] _maxHpList; }
    private:
    	int *_maxHpList;
    };
    
    Fighter::Fighter()
    {
    	_maxHpList = new int[50];
    
    	// assign your values here. I dont know any way of just saying maxHpList = { ... }
    	// if you're doing it this way, so it would help if you had a formula.
    }

    Don't I know it. Unfortunately, I don't know the exact formula, though I think I could come up with one if I really needed to. I just made it into a funtion in my main file, and it works fine now.

    If the array is going to be the same for each class produced and wont be altered, then you could make it a const static

    Code:
    #include <iostream>
    
    
    class foobar{
    private:
    	static const int Array[10];
    public:
    	int operator[](int n){return Array[n];}
    };
    
    const int foobar::Array[10] = {6,2,5,5,4,5,6,3,7,6};
    
    int main(void){
    
    	foobar f;
    
    	for(int i = 0; i < 10; ++i)
    		std::cout << f[i] << " ";
    
    }
