I got a qualification error of the member variable 'objectCount'. theThe compiler also returns 'ISO C++ forbids in-class intialization of non-const static member'. thisThis is the main class #include #include "Tree.h" using namespace std;:

#include <iostream>
#include "Tree.h"
using namespace std;

int main()
{
    Tree oak;
    Tree elm;
    Tree pine;

    cout << "**********\noak: " << oak.getObjectCount()<< endl;
    cout << "**********\nelm: " << elm.getObjectCount()<< endl;
    cout << "**********\npine: " << pine.getObjectCount()<< endl;
}

thisThis is the tree class which contains the non-const static objectCount:

#ifndef TREE_H_INCLUDED
#define TREE_H_INCLUDED

class Tree
{
    private:
        static int objectCount;
    public:
        Tree()
        {
            objectCount++;
        }
        int getObjectCount() const
        {
            return objectCount;
        }
    int Tree::objectCount = 0;
}
#endif // TREE_H_INCLUDED

C++ initialization of non constant static member variable??

I got a qualification error of the member variable 'objectCount'. the compiler also returns 'ISO C++ forbids in-class intialization of non-const static member' this is the main class #include #include "Tree.h" using namespace std;
