Array of structs Problem

[I BLcK I]

I don't think I've learned how to access all of an array of structs (that have pointers) through a member function. So, I'm trying to output all of the array's struct pointer to data , but I cant seem to figure out how to make the function call. So, how would I go about fixing this problem? thnx

main.cpp

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

int main(int argc, char * argv[])
{
	int n = atoi(argv[1]);
	utree * forest = new utree[n];
	
	forest.printArray(); // NOT the right call :/

	return 0;
}

func.h

struct node
{
	int data;
	node * parent;
	node();
	node ( int, node * );
};

class utree 
{
public:
	void printArray(int);
	int find(int);
private:
	node * root;
};

func.cpp

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

/*Construtors*/
node::node(){data = -1; parent = NULL;}
node::node(int n, node * link){data = n; parent = link;}


void utree::printArray(int n)
{
	for(int i = 0; i < n; i++)
	{
		cout << this[i].root->data;
	}
}

[vart]

in main

	for(int i = 0; i < n; i++)
	{
		forest[i].print();
	}

in class

void utree::print()
{
	if(root)
	{
		cout << root->data;
	}
}

your class is only one member of array - it does not know about over members

if you want a class that "knows" about collection of trees - you need to write a class
"forest" that will store the array (or better vector) of trees and will have possibility to printArray

As a side not - I hope you just skipped when posting required functions like constructor/destructor and operator= of your tree class and not missing them

Ya, I was kinda thinking of how it wasn't going to work, thnx. I didn't skip over those functions heh... I just started writing this I haven't wrote anything for a while :/ so i cant really remember much atm
