Need Help In C# Language. The Goal For This Exercise Is To Start Looking

need help in C# language. The goal for this exercise is to start looking at what needs to be done. In this step you’re going to examine both what the existing program already does as well as what we’d like it to do. We are NOT going to do any programming in this step. At this stage our goal is entirely just to understand the problem specification (as much as we can), and then to do a couple of activities in order to figure out both what we need to do and the overall structure of the program is. For this exercise you must do the following: Read through the problem specification The specification is linked to on the Lesson page. Play the finished game There is an executable file named something like Sample_Solution.exe which you should run. This is an example solution of the finished game, and you can use it to figure out what your program should do if the problem specification is not clear. IMPORTANT: Note that this game has NO GRAPHICS AT ALL WHATSOEVER. It’s a game, but it’s 100% console-based. Play the compiled game Open the provided starter project then compile and run the program. In a nutshell, it will be your job to fill in the missing features that Sample_Solution.exe has but this program lacks. As you play this verison of the game, note which features are missing. Skim the overall structure of the code Look through the source code for the program, and try to figure out how the program is put together, overall. As you’re doing this you need to specifically produce something that shows how the various classes inherit from one and other. You can draw this on paper (which you’ll then need to scan/take a picture of in order to hand in electronically) or you can use a Word .DOC (or a .PDF) with the below format showing what the inheritance is. Please make sure to name the file ClassHierarchy.DOC (or .PDF, or .JPG, or whatever) Example Format For Showing Inheritance: Imagine that the source code looks like this: class A { /* the implementation details are left out for brevity */ } class B { /* the implementation details are left out for brevity */ } class C : B { /* … */ } class D: B { /* … */ } class E: D { /* … */ } You can ‘outline’ the inheritance hierarchy like so: class A class B class C class D class E If you wanted to leave the word ‘class’ out of the outline that’s fine – I left them in here just so it’s clear what each line is. What you need to do for this exercise:   Fill in the file ClassHierarchy.DOC with something that clearly shows which classes inherit from which others Put this file in a very easy to find place in your .ZIP file, such as top folder. It’s expected that you’re going to fill out an ‘outline’ like the above, but drawing a picture like the instructor does in class would work too.

Need Help In C# Language. The Goal For This Exercise Is To Develop The

Need help in C# language. The goal for this exercise is to develop the skill of using the debugger to determine why your program(s) don’t work. This is a combination of knowing how to use the debugger itself, and being familiar with strategies for using the debugger to identify problems in your code. Within the starter project there is a folder named DebuggingExercises. It contains a complete, stand-along Visual Studio solution (i.e., it’s not connected to the main game program that you’re going to modify in this week’s exercises). During class / in the videos the instructor explained how to use the debugger (and demonstrated this using the FindMinimumValueInArray method). For this exercise you need to use the debugger to identify the error(s) in the HalfwayBetweenInputs and FillArrayWithFibonacci methods, and then use the debugger to try and figure out how the sortArray method works. What you need to do for this exercise:   Create a file named DebuggerExplanation.doc. Put this file in a very easy to find place in your .ZIP file, such as top folder. It’s expected that you’re going to fill out an ‘outline’ like the above, but drawing a picture like the instructor does in class would work too. For the HalfwayBetweenInputs and FillArrayWithFibonacci methods you need to clearly explain how you used the debugger to figure out what’s wrong with the methods. The focus here is on clearly explaining how you’re using the debugger (and using it effectively), NOT on actually finding the problem. (Chances are you can find and fix the problem without the debugger – in this exercise you’re focused on learning how to use the debugger, instead). For example, you might start one paragraph with: “HalfwayBetweenInputs: I ran the program (outside of the debugger) and noticed that when I typed in 20 and 10 I got the incorrect answer 5, instead of the expected 15. I then put a breakpoint on the first line in HalfwayBetweenInputs, and ran the program under the debugger. Once the program stopped I used the Step Over function to walk through the lines of code that get input from the user. After each input is obtained I used the locals window to verify that the program correctly received the number I typed in (it was). Next, I….” For the sortArray method you should write two things: First, write up a description of how to use the debugger to figure out how the algorithm works. Mention things like breakpoints, stepping in/over/out, examining values in locals/watch windows, etc, etc.   What you actually did while figuring this out was probably a bit of a jumble – you were, naturally, trying a bunch of things in order to puzzle stuff out. Go back, reflect on what worked, and try to build a narrative that explains how you could now show what the algorithm does (given your advantage of knowing more about what it does now). Second, write a short, concise, and clear explanation of how the method works. Your goal here is to provide an short, intuitive explanation; you should NOT just recap the method in a “line-by-line C# to English translation”. Imagine that you’re explaining this to someone who’s smart, but who has never programmed before. If this is wrong don’t worry about it (no points will be deducted). Mostly your instructor is curious about how much you understood. Remember that the goal is to learn to use the debugger, NOT to learn about this sorting algorithm)

Need Help In C# Language. Examining The Code Using The Debugger The Goal For

Need help in C# language. Examining the code using the debugger The goal for this exercise is to figure out what the program does in response to user input, and to figure out specifically how the program creates, updates, and removes a Rock object You need to figure out what the program does when the user chooses to create a Rock, using the debugger. While doing this you want to focus on figuring out two major actions that the program does: Object creation Where does the program create the new Rock object? How is that done?   (This will start to prepare you to be able to modify have the program in order to create a Fireworks object) Updating all the currently existing objects In addition to creating a Rock object the program also moves along any projectile objects that currently exist in the game. In other words, the game has to move any previously thrown rocks, etc.   Which method(s) make this happen? How do they do this? When you implement the Fireworks class you’ll need to understand how this is done. Concrete Deliverable: A Fuzzy Trace Table If you’ve taken BIT 115 then you’re familiar with the idea of a trace table: it’s a table that lists the line numbers of the lines that a program execute, in the exact same order that the program executes them. We want to use that same sort of idea, but we do NOT want that line-by-line level of detail. Instead, we’re going to use a ‘Fuzzy Trace Table’, which is a brilliant name that I just made up right now. In the fuzzy trace table you’re only going to have two columns: the first column is the method that gets run, and the second column is for any comments that you want to leave.Here’s an example: Example program class Program { public static Main() { BizLogic ap =new BizLogic(); app.GetUserInput(); app.DoSomethingUseful(); } } class BizLogic { private int numToStore; public void GetUserInput() { // ask the user for input, store it into numToStore } public void DoSomethingUseful() { // using numToStore, do something complicated } } The corresponding ‘Fuzzy Trace Table’ might look something like the following: Method Notes/Comments main GetUserInput main When GetUserInput finishes we go back to main. List this even though it’s just a quick visit DoSomethingUseful HERE’S WHERE WE CALCULATE THAT REALLY DIFFICULT-TO-CALCULATE NUMBER!! There is a Word .DOC provided on the Lesson page that you can use as a starter file for this exercise. Feel free to make your own 2-column table if you prefer. What you need to do for this exercise:   Use the debugger to walk through the program, creating fuzzy trace tables as you go. Set a breakpoint in main. Start the program up (so that there are no projectile objects), and walk through what happens when the user decides to create a single Rock object. Document your work using a fuzzy trace table. Save your work for this part into a file named ObjectCreation.DOC. Create several more projectiles, so that you’ve got 2-3 projectiles that need to be moved each round. Starting wherever you think is most appropriate, do a second, separate fuzzy trace to determine which parts of the program actually move the projectiles each round.Save your work for this part into a file named ProjectileUpdating.DOC. Make sure that the files are very easy to find – I recommend putting them at the top level folder in your ..ZIP file. Make sure thaty The goal here is for you to develop an overall understanding of how the program works, and how the Rock objects are created and moved during the game. The instructor realizes that what one person needs to do to develop this understanding may be different than what someone else needs to do; as long as you’ve clearly demonstrated that you understand these things you can expect to do well, grade-wise. Make sure that you clearly answer the questions in the Object Creation / Updating all the currently existing objects sections (above) using your Fuzzy Trace Table. Actually putting your answers into the trace table (on or near the line(s) that answer these questions would be a great way to clearly convey your understanding.

Use Matlab. Write A Script File To Find A Root Of The Function 10𝑥2−10𝑥 0.1sinh(𝑥) 𝐶10×2−10x 0.1sinh⁡(x) C

use matlab. Write a script file to find a root of the function 10𝑥2−10𝑥 0.1sinh(𝑥) 𝐶10×2−10x 0.1sinh⁡(x) C for C = -400 using Newton’s Method with initial guess 𝑥0=1×0=1. Note that sinh is the hyperbolic sine function. You will need to know the derivative of sinh (and cosh) for the next Test. Your script should not use any of the built-in Matlab functions fsolve, fzero, or roots. Your script should print out to the Command Window the approximation to the root after exactly five iterations of Newton’s Method. You can use fprintf (showing the value to at least 4 decimal places) or disp or just let the value be displayed by omitting the semicolon. Nothing else should be printed out to the Command Window. Requirements, suggestions and reminders that you will not get given in the Test: For this question put everything into the script file (ie, do not attempt to use one of your Newton’s Method functions) – it is good practice to write it again, and in the test most people find it easier to just do a short script than to have to do a separate function file.   Remember that the initial guess does not count as an iteration: you need to do 5 actual iterations of Newton’s Method to get the right answer.   You have been asked to do exactly 5 iterations. Do not be tempted to increase this to improve the approximation.You also have no choice over the initial guess. function
