Programming is one of the subjects to master the knowledge base, understandingprogramming models such as procedural programming, object-oriented programming, andevent-oriented programming, the structure of a program, data, basic data, at the sametime to introduce to students the knowledge of IDE, the functions of the IDE and somestandard rules, rules of naming in code At the same time, it helps students gainknowledge to build basic applications

This report includes the following:

CHAPTER 2 PROBLEMS RELATED TO PROGRAMMING METHODS AND IDE.LO2 Explain the characteristics of procedural, object-oriented and event driven

programming, conduct an analysis of a suitable Integrated Development Environment (IDE) CHAPTER 3 IDE problems, debugging procedures, and coding standards.LO3 Implement basic algorithms in code using an IDE

2.1.1Procedure-Oriented Programming(POP):

POP is a way to establish information Procedural programming is the main focus for completing tasks sequentially supporting the concept of procedure calling Procedures (regular form or subroutine) simply contain a series of steps

Calculations be done Save control of the program's organizational flow If the program is extensible, it is structured in a number of small units called functions, which share data system-wide

This purpose is to simplify the structure of the program.

For example: Create a recursive function to calculate the factorial of a

number The first is to create the main function:

Button" to click the result and delete the result Data A when entering them shouldenter a non-zero number if entering 0 it will say "Or enter another 0"

Application" it will get an error as shown above.

To fix that error, I will Declare the library "using System.Windows.Forms;" as shown below

robust applications(M4)

Debugging:

Debugging is the process of finding out the error or the cause of the error (where thebug is) to have a direction to fix the error (fix the bug) Debugging is not only to removeerrors from the program, but more importantly, to help the programmer betterunderstand the execution of the program A programmer without the ability to debugeffectively is like being blind

It is normal for any programmer to have an error in thousands of lines of code Theprogram may not run according to the programmer's intention, or run the wrongfunction it is prescribed, causing the program to be rated shoddy So when there is anerror, the programmer must debug to fix the error to help the program run well

IDE debugger:

Advantages.

IDEs allow programmers to write code to develop applications In addition, it alsointegrates a lot of different software development tools such as: code search support, compiler and interpreter creation, code organization and sorting

In addition, the IDE helps to optimize the coding process It provides a suitable interface for code generation and helps to automate the programming steps In simpler terms, an IDE is an environment that integrates the functions of many processes together It allows users to use popular programming languages such

as Java, Python, etc Besides, the IDE environment also supports programmers

to install plugins to make the coding process simpler

What makes IDEs superior is the ability to chain pre-assigned groups of code from one or more people Users simply build hierarchies and systems together incodes The IDE also comes with both an intuitive debugger and checker, which greatly saves time re-testing the program

Disadvantages.

Software is difficult to install and consumes memory space of the computer

Sometimes the IDE can't find the error and fix it

and debugging IDE debugging found error

Figure3-25 The program is out of error.

When you review the program, you will realize that there was an error

if you have a big program this will be a lot of time and hard

Manual debugging is used by a few people and programmers very rarely

is out of error.

the individual(D4).

Define:

Coding conventions: A coding convention is a set of guidelines for a

language-engineering language that recommends setting styles, practices, and methods for eachaspect of programs written in that language These conventions typically include file organization, margining, comments, declarations, statements, spaces, naming conventions, set implementations, setup rules, setup rules, methods best in

architecture, etc This is a guide to quality structural software Software developers should follow guidelines to help improve the readability of their source code and make

it easier to maintain Coding conventions are applicable only to human maintainers andpeer reviewers of a project software Conventions can be formalized in a well-documented rule that the entire team or company follows, or can be as informal as information that lowers an individual's code Coding conventions are not enforced by the compiler

The risk of project failure is minimized

Many times it happens that IT projects fail due to problems while developing software Implementing code quality standards reduces many problems and the risk of project failure

Minimum complexity

If a code is complex, then the chances of it being error-prone are higher Coding standards make it possible to develop less complex software programs and thus reduce errors

Easy to maintain

If programming standards in software engineering are followed, the code will be consistent and easily maintainable This is because anyone can understand it and can modify it at any time

The benefit of coding standard for a team or personal:

Implementing code quality standards reduces many problems and the risk of project failure If a piece of code is complex, the chances of it being error-prone are higher Coding standards make it possible to develop less complex software

the same way, it would be easier for everyone to predict and be more organizedRead more codes Declare variables in the usual place, in the usual order,

declared in the same and usual way

For example, my current employer has a very specific standard for how digital

identities should be declared We have to capitalizeLikeThis I hate it Terrible

But everyone does it the same way, allOfTheTime It becomes completely 100% predictable And that's better

5.1 Outline the coding standard you have used in your code(P5).

Variable:

Avoid using multiple variables as a whole to avoid influence use only when necessary

• I will put captions for each section

• We need names that are memorable and meaningful

Some notes in naming:

• Do not reuse the same names or change only a few characters such as capital letters In many cases it will lead to confusion

• Do not set up two namespaces with the same name, but only change it with uppercase letters,

so there are more numbers

• Don't build a method with the same parameters and only different cases

• Abbreviations should not be used in IDs or parameter names

• When naming abbreviations, you can use Pascal case or Camel case for naming

Naming rules:

Common capitalization styles:

Pascal Case: The first letter of the identifier and the first letter of each subsequent word must be capitalized For names of three or more characters, use Pascal Case.

Camel Case: The first letter in the identifier is a lowercase letter and the first letter of the following hyphen must be capitalized.

All characters in the identifier must be capitalized Use this rule for identifiers with 2 characters or less

Named Assembly and DLL: Use a name to collectively describe the internal functions of the

Assembly

Use Pascal syntax to name the namespace.

Use the prefix of company and organization names to limit the conflict

of namespaces with the same name

For example:

Name the class, struct, and interface:

Use nouns or noun phrases to name classes, struct Use Pascal's case.Name the interface an adjective phrase, or you can use a noun or a noun phrase

Do not use the prefix "C" for class names

Should end the name of the inheriting class with the name of the base class.Use the "I" prefix for the interface name

For example: Name the class

Name the interface:

Name the method, property, and field of a type:

Name the method:

Use verb or verb phrase for method names

Name properties

Use nouns, noun phrases or adjectives

Use Pascal case to name the field.

Use nouns, noun phrases or adjectives

Do not use prefixes for field names

Indent:

it makes the source code easier to learn, easier to understand it makes the source code easier to learn, easier to understand

Every substatement inside a block must be indented

The opening braces must be in a straight column with the closing brace

we need to avoid confusing using verbose encodings, length of functions we shouldkeep to a minimum and easy to understand

For example: Solve equations of degree 1:

Figure3-28 For example.

Some naming ways for objects in “winform”:

OJECT

LinkLabel llbl

Table 3-1: Some coding standard

For example: I design a program that calculates quadratic equations, by using wiform.

I designed the Form as follows:
