In this program we will see how to generate Fibonacci sequence.Problem StatementWrite 8085 Assembly language program to generate the first ten elements of the Fibonacci sequence using registers only and store them in memory locations 8050H to 8059H. DiscussionThis program will generate the Fibonacci numbers. The Fibonacci numbers follows this relation F(i) = F(i - 1) + F(i - 2) for all i >2 with F(1) = 0, F(2) = 1.InputIn this case we are not providing any input, this program will generate ten Fibonacci numbers.Flow DiagramProgramAddressHEX CodesLabelsMnemonicsComments800021, 50, 80STARTLXI H 8050H Pointer to the OUT-BUFFER8003AFXRA A Clear accumulator and reg.

UItableViewController and UIViewController are two different objects of iOS UIKit framework. Both are used for different purpose.A UIViewController class manages a ViewContoller which is responsible for actions that happen within that View controller. This class is aware of actions that happen on view controller, like ViewDidLoad, ViewWillApper, ViewDidAppear, ViewWillDisapper, ViewDidDisapper.Whereas, A UITableViewController is responsible for managing a table, it's data and it's events using UITableViewDataSource, UITableViewDelegate.A UITableViewController conforms to UIViewController, UITableViewDataSource and UITableViewDelegate to implement table view.Below is an example of a class implementing UIViewController.class ViewController : UIViewController { @IBOutlet weak var sampleView: UIView! ...

For random numbers in a range, you need to use the RAND() method from MySQL. The syntax is as follows for update −UPDATE yourTableName set yourColumnName=value where yourColumnName2=(SELECT FLOOR(1+RAND()*3));In the above query, the statement FLOOR(1+RAND()*3) generates the number between 1-3 and update the column.To understand the above syntax, let us first create a table. The query to create a table is as follows −mysql> create table updateRowWith1To3 -> ( -> Id int, -> Name varchar(100) -> ); Query OK, 0 rows affected (0.47 sec)Insert some records in the ...

Now let us see a program of Intel 8085 Microprocessor. This program will convert 8-bit numbers to two digit ASCII values.Problem StatementWrite 8085 Assembly language program where an 8-bit binary number is stored in memory location 8050H. Separate each nibbles and convert it to corresponding ASCII code and store it to the memory location 8060H and 8061H.DiscussionIn this problem we are using a subroutine to convert one hexa-decimal digit (nibble) to its equivalent ASCII values. As the 8-bit number contains two nibbles, so we can execute this subroutine to find ASCII values of them. We can get the lower nibble ... Read More
To set the background color for a navigation bar we can either do it programmatically or through the storyboard if it is on storyboard.Method 1Let's see how to change the background color of a navigation bar through the storyboard editor.Create a new project, select it's view controller and embed in navigation controller.Select the navigation bar and go to It's attribute inspector.This is how it looks in the Xcode 10. You can select the tint color from there and it will be changed for the navigation controller.Method 2Programmatically changing the navigation background.To programmatically change it, go to the view controller and ...

(What caused this?)I didn't call her because I'm busy.PurposeWhy? (What was the reason for doing ... Read More
You can strip time component from datetime with the help of DATE() function. The syntax is as follows −SELECT DATE(yourColumnName) from yourTableName;To understand the above concept, let us first create a table −mysql> create table StripComponentDatetimeDemo -> ( -> YourDateTime datetime -> ); Query OK, 0 rows affected (0.60 sec)Let us now insert some records in the table. The query is as follows −mysql> insert into StripComponentDatetimeDemo values(date_add(now(), interval 1 day)); Query OK, 1 row affected (0.13 sec)Display records with the help of select statement. The query is as follows displaying ... Read More
