Magento 2 Get shipping and billing address of customer after order placed?

Solved my problem by following edit in below file:

/vendor/magento/module-sales/view/frontend/templates/email/items.phtml

$_order = $block->getOrder()
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$formatedAddress = $objectManager->get('\Magento\Sales\Model\Order\Email\Sender‌​\OrderSender');
print‌​_r($formatedAddress-‌​>getFormattedBilling‌​Address($_order)); 
print_r($formatedAddress->getFormattedShippingAddress($_orde‌​r));

You can add this piece of code in the file:

<?php /** @var $_order \Magento\Sales\Model\Order */ ?>
<?php $_order = $block->getOrder() ?>
<?php $billingAddress = $_order->getBillingAddress(); ?>
<?php $shippingAddress = $_order->getShippingAddress(); ?>

With $billingAddress now you can get address e.g:

<?php echo $billingAddress->getStreet() ?>
