Chapter 1. State your simple business problems to be solved
1. Overview about Algorithm
Algorithms give us the most ideal option of accomplishing a task to improve the efficiency of a computer program, proper utilization of resources. What algorithm mean?
- An algorithm is a finite sequence of well-defined, computer-implementable instructions, typically to solve a class of specific problems or to perform a computation.
- Algorithms are always unambiguous and are used as specifications for performing calculations, data processing, automated reasoning, and other tasks. In contrast, a heuristic is a technique used in problem solving that uses practical methods and/or various estimates in order to produce solutions that may not be optimal but are sufficient given the circumstances.
2. Represent a small and simple problem
Firstly, I will introduce the C# language, it used in algorithm to solved problem Figure 2. C# language
- C# is a general object-oriented programming (OOP) language for networking and Web development. C# is specified as a common language infrastructure (CLI) language.
- In January 1999, Dutch software engineer Anders Hejlsberg formed a team to develop C# as a complement to Microsoftâs NET framework. Initially, C# was developed as C-Like Object Oriented Language (Cool). The actual name was changed to avert potential trademark issues. In January 2000, NET was released as C#. Its NET framework promotes multiple Web technologies.
Chapter 2. Analyse the problem and design the solutions by the
use of suitable methods
1. Analyse the problem
There is a basic example of a problem that can solve by an algorithm.
- A teacher wants to manage the grades of his class. He asks you to help him to create a small application to manage them. He needs to enter the name, ID, grade of the students. Then he needs to print information and grade together.
- After read clearly the scenario, I solved it by using an algorithm based on C# language to create a program must have full option that satisfy the requirement of teacher. We need to create an application to enter name, score, ID.
2. Flowchart
Flowchart 1. Main of application
Flowchart 2. Menu list of application Explain (pseudo code): Step 1: START Step 2: PRINT (âInput total student (3-30)â) Step 3: PRINT (â1. Input informationâ) Step 4: PRINT (â2. Show informationâ) Step 5: PRINT (â3. Exitâ) Step 6: PRINT (âInput your choiceâ)
Option 1. Input information of students Explain (pseudo code): Step 1: START Step 2: DECLARE the variable i Step 3: Input n Step 4: WHILE n < 3 | n > 30 is true, return step 3 Step 5: SET i = 0 Step 6: WHILE I < n is true, repeat 8 through step 11
Explain (pseudo code) Step 1: START Step 2: DECLARE the variable i Step 3: SET i = 0 Step 4: WHILE i < n is true, repeat step 5 through step 6 Step 5: PRINT ID[i], grade[i], name[i] Step 6: MOVE UP i by 1 Step 7: STOP
Chapter 3. Demonstrate the compilation and running of a
program
1. Introduce how the program is solved and screen shots source code of the
result
The solution here is I use functions called âswitch-caseâ, each of which has an algorithm to process the program. And the program use âdo-whileâ function to check the condition. Firstly, I create variables that using strings to store information into arrays, using integer âIâ for âfor-loopâ functions, using integer ânâ to get total of students, using Boolean to check and âkâ for âswitch-caseâ. Figure 3. Variable
Void 1. Input information Figure 4. Input information I used the âfor-loopâ function and I used the while-loop structure here, if the grade is less than 0 and more than 10, it will force the user to reenter, because the point ladder always starts from 0â10. So, if the user enters the right grade, it will move to enter IDs.
Void 3. Main Figure 6. Main
I start with âInput total students(3-30)â and SET the âdo-whileâ is (n<3 or n> 30). After that I print the menu list has all of things that teacher needs. In the âswitch-caseâ ⢠Case 1 is mandatory, run Input () function, after that, assign check=true and return to the menu ⢠If user choose case 2, it will run showinfo () function, it happens if user input case 1 first. Finish case 2, return to the menu. ⢠Then in the case 3, it is the way to quit this application.
2. Result of menu function
Figure 7. Result of menu function After enter 3 students Example: When you select option 2, you will get a list of all student IDs and grades
When the user chooses option 2, the program will display on the screen all the studentâs information including the studentâs grade and ID Figure 9. Result of option 2 Show information
3. Explain briefly what Software Development Life Cycle
Software Development Life Cycle (SDLC) is a process used by the software industry to design, develop and test high quality softwareâs. The SDLC aims to produce a high-quality software that meets or exceeds customer expectations, reaches completion within times and cost estimates. ⢠SDLC is the acronym of Software Development Life Cycle. ⢠It is also called as Software Development Process. ⢠SDLC is a framework defining tasks performed at each step in the software development process. ⢠ISO/IEC 12207 is an international standard for software life-cycle processes. It aims to be the standard that defines all the tasks required for developing and maintaining software
Chapter 4. Evalutate how the problem is solved from the designed
algorithm to the execution program written by a specific
programming language
