[C++] HELP. trying to create a binary tree structure. crash when adding nodes.

struct TreeNode {
       int item;     // The data in this node.
       TreeNode *left;  // Pointer to the left subtree.
       TreeNode *right; // Pointer to the right subtree.
};
int main (void){
	TreeNode myTree;
	myTree.item = 1;
	myTree.left->item = 2;
	myTree.right->item = 3; //it starts crashing here. 
	myTree.left->left->item = 4;
	myTree.left->right->item = 5;
	myTree.right->left->item = 6;
	myTree.right->right->item = 7;
	return 0;
}

it compiles fine, and i think the syntax is fine. but it crashes when i run it. i removed the lines starting at item = 3, and it will run fine.

Kanang imong TreeNode *left ug *right unsa ang reference type iyang gi-point ana?

[ares623]

referencing another TreeNode. Solved na, i have to initialize what the pointers are pointing at. Never did understand how to handle referencing in C/C++.. hehe.
thanks bro.

You're welcome.

OT : Why naggamit ka ug struct in C++? Para nako it should be better use the class statement because it is more powerful and OOP than struct.
