Graded Discussion Board
Mobile application development industry in the last few years has grown worldwide and it has changed the way businesses function worldwide. Enterprises also want to align mobile apps according to their productivity in recent times. Rapid innovation in mobile devices across platforms has given the challenge to mobile application developers to write several versions of an application for many different platforms using a single language and many pieces of reusable code. As a mobile application developer when you had realized your mobile app idea, it's time to validate it, understand the target market, and narrow down the platform on which you ideally would like to build your mobile application. As soon as that is decided, it’s time to select a programming language, keeping in mind your business strategy to make either native or hybrid platform apps.
So considering you a mobile application developer you are given the following requirements for your mobile application development
User friendly GUI
Full access to any platform spectrum including platform specific capabilities
Libraries inclusion from different service providers
Ahead-of-time (AOT) compilation on applications
Negligible startup time
Increased memory sharing feature
Improved performance
You will suggest that either you will go for hybrid or native application development. After that as per your selected application type you will write name of programming language and framework you use and then you justify your choice with reasons. Your answer must be brief

Answer:

Here is the Python program:  

def measure_string(myStr): #function that takes a string as parameter  

 if myStr == '': #if the string is empty (base case)  

      return 0  #return 0  

  else: #if string is not empty  

      return 1 + measure_string(myStr[0:-1]) #calls function recursively to find the length of the string (recursive case)  

#in order to check the working of the above function the following statement is used    

print(measure_string("13 characters")) #calls function and passes the string to it and print the output on the screen      

Explanation:

The function works as following:  

Suppose the string is 13 characters  

myStr = "13 characters"  

if myStr == '': this is the base case and this does not evaluate to true because myStr is not empty. This is basically the alternate of  

if len(myStr) == 0: but we are not supposed to use len function here so we use if myStr == '' instead.  

So the program control moves to the else part  

return 1 + measure_string(myStr[0:-1])  this statement is a recursive call to the function measure_string.  

myStr[0:-1] in the statement is a slice list that starts from the first character of the myStr string (at 0 index) to the last character of the string (-1 index)  

This statement can also be written as:  

return 1 + measure_string(myStr[1:])

or  

return 1 + measure_string(myStr[:-1])  This statement start from 1st character and ends at last character  

This statement keeps calling measure_string until the myStr is empty. The method gets each character using a slice and maintains a count by adding 1 each time this statement is returned.The function breaks string into its first character [0:] and all the rest characters [:-1]. and recursively counts the number of character occurrences and add 1. So there are 13 characters in the example string. So the output is:  

13

Explanation:

An SQL retrieval query contains six clauses which are executed in an orderly sequence. These clauses include; SELECT, FROM, WHERE, GROUP BY, HAVING and ORDER BY.

The select clause enables us specify the data we want to retrieve. This statement is the starting point of SQL queries.

The FROM statement comes second and specifies the table the data is being retrieved from.

The WHERE clause helps us limit the data to those that meet a particular condition.

The GROUP BY statement helps group your information in a more meaningful way.

The HAVING clause puts a condition on your group.

The ORDER BY statement orders your information in descending order or ascending order.

Answer:

Flowchart of an algorithm (Euclid's algorithm) for calculating the greatest common divisor (g.c.d.) of two numbers a and b in locations named A and B. The algorithm proceeds by successive subtractions in two loops: IF the test B ≥ A yields "yes" or "true" (more accurately, the number b in location B is greater than or equal to the number a in location A) THEN, the algorithm specifies B ← B − A (meaning the number b − a replaces the old b). Similarly, IF A > B, THEN A ← A − B. The process terminates when (the contents of) B is 0, yielding the g.c.d. in A. (Algorithm derived from Scott 2009:13; symbols and drawing style from Tausworthe 1977).

Answer:

virtual reality

Explanation:

Virtual reality is basically a simulated or virtual environment. This environment is implemented by compute technology for the users that can interact with the virtual 3 dimensional objects instead of just watching them on the screen. With the use of multi-sensory input and output devices the senses of the user are simulated.

Virtual reality devices are the products used for interacting with a virtual environment for the users. Some of the multisensory input/output devices include:

data gloves

jumpsuits

track pads

joysticks

treadmills

multi-speaker audio

visual displays

controller wands

head set

For example a data glove enables the users to interact with virtual objects and feel the object rather than just a movement of hand in the air and it is also used in virtual gaming. Jumpsuits are also used to feel sensations in the virtual reality environment. It stimulates different body parts in response to any action taken by user in a virtual environment.

Complete Question:

Even if you skipped all the requirements analysis steps, the two steps guaranteed to be completed in any software development are;

Group of answer choices

A. policy and procedure development

B. use case activity diagram testing

C. method design and coding

D. data conversion and user training

Answer:

C. method design and coding

Explanation:

A software development life cycle (SDLC) can be defined as a strategic process or methodology that defines the key steps or stages for creating and implementing high quality software applications. There are six (6) main stages in the creation of a software and these are;

1. Planning.

2. Analysis.

3. Design.

4. Development (coding).

5. Deployment.

6. Maintenance.

Among the listed stages, there are two (2) most important stages which cannot be ignored in the creation of a software application are.

Hence, even if you skipped all the requirements analysis steps, the two steps guaranteed to be completed in any software development are method design and coding.

I. Method design: this is the third step of the software development life cycle, it comes immediately after the analysis stage. This is the stage where the software developer describes the features, architecture and functions of the proposed solution in accordance with a standard.

II. Coding (development): this is the fourth step in the software development process and it involves the process of creating a source code which would enable the functionality of the software application.

Answer:

integer

Explanation:

The expression can be implemented as follows:

x <- 4L

class(x)

Here x is the object. When this expression is executed in R, the class "integer" of object 'x' is determined by the class() function. R objects for example x in this example have a class attribute determines the names of the classes from which the object inherits. The output of the above expression is:

"integer"

Here function class prints the vector of names of class i.e. integer that x inherits from. In order to declare an integer, L suffix is appended to it. Basically integer is a subset of numeric. If L suffix is not appended then x<-4 gives the output "numeric". Integers in R are identified by the suffix L while all other numbers are of class numeric independent of their value.

Answer: A. > interesting.txt

Explanation: From the command line, one can perform numerous tasks from navigating into a directory, creating a new directory, deleting files, create files, modify files and so on using simple commands. In the scenario above, after using a common which is used to produce an output on the screen, such as the 'echo' command, one may wish to save the file giving the user the ability to access the file later. Since it is stated the file name 'interesting.txt' given to the file does not currently exist, appending the sign > saves the file. If the filename already exists, it will overwrite the existing content.

Answer: Circle class representing circle objects which have a radius, center x, and center y. It included overlaps and draw methods. Then, we wrote a Colorfulcircle class which included a Color property and overrode the draw method of Circle. For this assignment, you are asked to create a ColorfulBouncing circle class. Begin with the versions of Circle and ColorfulCircle uploaded to Canvas ColorfulBouncingCircle should extend ColorfulCircle, Unlike the other Circle classes, it will include a velocity for the x and y axes. The constructor for ColorfulBouncingCircle includes these parameters: public colorfulBouncingcircle (double radius, double centerx, double center Color color, double xVelocity, double yvelocity) Note that we are treating x as increasing to the right and y as increasing down, as with Java's graphics coordinates system. This was also seen with Circle's draw method. ColorfulBouncingCircles will bounce around in a playing field which the tester will provide. The Colorful Bouncinesicle class should have a public static method to set the playing field width and height: public static void setPlayingFieldsize (double newwidth, double newHeight) ColorfulBouncingCircle will also include a method which should alter its center and center with each time tick (similar to a metronome's noise guiding a musician to play a song). The circle's x position should be altered according to x velocity and y position according to y velocity. However, before changing the positions, check if the center position would, after moving, be either less than 0 or greater than the playing field dimensions. If so, instead of changing the center position, alter the velocity. If the ball hits the top or bottom, the sign of its vertical velocity should be flipped: if it hits the left or right, its horizontal velocity sign should be flipped. If it hits a corner, both should be. Notice that velocity may be positive or negativel The tick method which will be called by the tester is defined in this way:

public void tick() Finally, we should override the overlaps method to make balls bounce away from each other. You should call the super method to see if your circle overlaps another circle. If so, alter this circle's velocity according to its center relative to the other circle. If this circle" is above or below the "other circle," flip the sign of "this circle's" vertical velocity. If it's to the left or right, flip the horizontal velocity As before, both may be flipped. This is NOT the same as a true elastic collision, but it should be simpler for you to implement. The sign flipping will sometimes cause the balls to "vibrate" when caught between each other. Please review the velocity changing rules carefully; they are easy to get wrong!! To review: Write the ColorfulBouncineCircle class, where you should write the constructor setPlayingfield Size, and tick methods, and override the overlaps method, each according to the above descriptions. You should not have to write any code which draws; instead, a test program will be provided which will animate ColorfulBouncingCircles based on your implementation. For every time tick, the test program will compare every circle against every other circle using the overlaps method. The test program will ask you to press Enter in the console to launch the automated tests which will assign a tentative score based on your implementation. DO NOT ALTER the Circle OR Colorful Circle files!!

B) People with low uncertainty avoidance

Explanation:

Uncertainty avoidance is how cultures differ on the amount of tolerance they have of unpredictability. Mostly, uncertainty avoidance deals with technology, law, and religion. People with low uncertainty avoidance cultures accept and feel comfortable in unstructured situations or changeable environments and  tend to be more pragmatic and more tolerant of change. People in cultures with high uncertainty avoidance try to minimize the occurrence of unknown and unusual circumstances.

Answer:

input number  

calculate modulus of the number and 5  

compare outcome to 0  

if 0 then output "divisible by 5"  

else output "not divisible by 5"

Explanation:

The modulo operator is key here. It returns the remainder after integer division. So 8 mod 5 for example is 3, since 5x1+3 = 8. Only if the outcome is 0, you know the number you divided is a multiple of 5.
