Answer 1

create your custom module to run cron job. I have explain you how to do this

1. create/open your module config.xml file and put below code in

To run a cron job every 48 hours.The fields denote (from left-to-right):Minute, Hour, Day of Month, Month, Day of Week. The "*/2" in the Day of Month field means "every two days".

<config>
    <modules>
        <Cancelorder_Cron>
            <version>0.0.1</version>
        </Cancelorder_Cron>
    </modules>
    <global>
        <models>
            <Cancelorder_Cron>
                <class>Cancelorder_Cron_Model</class>
            </Cancelorder_Cron>
        </models>   
    </global>           
    <crontab>
        <jobs>
            <Cancelorder_Cron>
                <schedule>
                    <cron_expr>0 2 */2 * *</cron_expr>
                </schedule>
                <run>
                    <model>Cancelorder_Cron/cron::cancelUnprocessedOrders</model>
                </run>
            </Cancelorder_Cron>
        </jobs>
    </crontab>
</config>

2. create/open your module model file Cancelorder/Cron/Model/Cron.php And add below code

<?php 
class Cancelorder_Cron_Model_Cron 
{   
    public function cancelUnprocessedOrders($observer)
    {                 
      $orderCollection = Mage::getModel('sales/order')->getCollection()
      ->addAttributeToFilter('status', array('neq' => Mage_Sales_Model_Order::STATE_PENDING_PAYMENT))
      ->addAttributeToSelect('*');
      $orders ="";
        foreach($orderCollection->getItems() as $order)
            {
              $orderModel = Mage::getModel('sales/order');
              $orderModel->load($order['entity_id']);


              if(!$orderModel->canCancel())
              continue;

              $orderModel->cancel();
              $orderModel->setState(Mage_Sales_Model_Order::STATE_CANCELED, true);
              $orderModel->save(); 
        }
    } 
}
