Sending pointer to function

murva (49)
Hello,

I have an object with three pointers to another three objects.On my main, I am trying to send a pointer to this object. The problem is that the internal pointers are not returning the values. Could you please advice me what the problem is?
Thanks

#include <iostream>
#include <cmath>

using namespace std;

class nodeTree
{
public:
	int value;
	nodeTree *son1,*son2,*son3;
	nodeTree(int v){son1=son2=son3=NULL;value=v;}
	void add(nodeTree newa,nodeTree newb,nodeTree newc)
	{
		this->son1=&newa;
		this->son2=&newb;
		this->son3=&newc;
	}



};

void calcMax(nodeTree *);

int main()
{
	nodeTree myRoot(2);
	nodeTree a1(4);
	nodeTree a2(5);
	nodeTree a3(6);

	myRoot.add(a1,a2,a3);
	cout<<myRoot.son1->value;//prints ok

	

	calcMax(&myRoot);

	
	


}

void calcMax(nodeTree *t)
{


	cout<<t->son1->value; //garbage, not expected value,why?



}

void add(nodeTree newa,nodeTree newb,nodeTree newc)
Parameters are passed by value. It should be:
1
2
3
4
5
6
 
	void add(nodeTree *newa, nodeTree *newb, nodeTree *newc)
	{
		son1=newa;
		son2=newb;
		son3=newc;
	}
