C++ (Cpp) delValue Examples

Example #1

File: Task1.cpp Project: alexander-podshiblov/HomeTasks_Programming

int main()
{
	Tree *head = new Tree;
	head->value = -32999;
	head->left = NULL;
	head->right = NULL;
	head->prev = NULL;

	char c = 0;

	while (c != '0')
	{
		printf("\n	0 Exit\n	1 Add value to tree\n	2 Delete value from tree\n	3 Exist?\n	4 Print\n	");
		scanf("%c", &c);
		if (c == '\n')
			scanf("%c", &c);
		if (c == '1')
			addValue(head);
		if (c == '2')
			delValue(head);
		if (c == '3')
			existence(head);
		if (c == '4')
			printEl(head->left);
	}
	
	
	delTree(head->left);
	delete head;	
	return 0;
}

Example #2

File: QKeyList.cpp Project: Deledrius/PlasmaShop

    QMenu menu(this);
    QAction* addObjItem = menu.addAction(tr("Add Item"));
