1. Procedural programming A programming model that divides a program into functions or chapters sub program. Each program can also be divided into several programs others to simplify their work. Advantage - Procedural programming is great for general purpose programming. - Codified simplicity with ease of implementation of compilers and interpreters - A large number of books and online course materials have written procedurally oriented algorithms, making it easy to learn. - The source code is portable, so it can also be used to target another CPU - The code can be reused in different parts of the program, without having to duplicate it - Through procedure-oriented programming technique, memory requirements are also reduced - Program stream can be watched easily Disadvantage - Large program code is harder to write, harder to maintain, more buggy.
- Procedural code is often not reusable, which may require rewriting the code if it needs to be used in another application.
- Difficult to describe with real-world objects
- Procedure-oriented programs focus on manipulation instead of data, which can cause problems in some data- sensitive cases
- Data is displayed for the entire program, making the data security not very good. 1.2 Object Oriented Programming: is a computer programming model that designs software around data, or objects, instead of functions and logic. Inheritance It allows to construct a new class based on existing class definitions. This means that the parent class can share data and methods with the child classes. Subclasses do not have to be redefined, in addition, they can extend inherited components and add new components. Reuse the source code in an optimal way, taking advantage of the source code. Some common types of inheritance: single inheritance, multiple inheritance, multi-level inheritance, hierarchical inheritance. Polymorphism Polymorphism is a concept where two or more classes have the same methods but can be implemented in different ways. Abstraction abstraction means choosing the properties and methods of the object needed to solve the problem you are programming. Because an object has a lot of method properties, but for a particular problem, it is not necessary to select them all. Encapsulation Related data and methods are encapsulated into classes for ease of use and management. That is, each class is built to perform a specific set of functions for that class. Advantage
- Due to its modularity and encapsulation, OOP provides easy management
II. implement basic algorithms in code using an IDE In this composition, I'll introduce you to the zoo management operation that I developed. There are 4 function. I've added features to add, edit, cancel and login in windows form below will be each illustration and how the features work. Login: as you can see an account and word are needed to pierce the app, enhanced security anti-hacking.
there is no other "else" case so if you enter it wrong you won't be able to enter form 1. ADD data, just enter the information and click on the add tab to easily add objects
As you can see, the click button is used to fit objects into the table after it has been imported. with data types of type string for insert name and type and int 32 for the number so if you class it wrong it will not be suitable to add data. The line Animal animal = new Animal(name, type , amount); for add and show the object in board. Edit: transvalue
In the editing section, you can edit each content right on the table, or you can edit an entire line by pressing that line and entering data in the cell and opting edit. you re-enter the same objects as the Add case section. the program will replace that line with null and add new objects. DELETE: Just point to the line of the object to be deleted and then press the delete button to delete the object from the table
To delete the object, you need to select the correct line and press the delete button. The program will automatically delete all data with the command "RemoveAt" in the listAnimal table. Then the dgvAnimal will return result = null. III. Debug process
the program will jump directly to the error point where you set the breakpoint. Example of running debug process
Step into: Press f10 to let the program check the next line. As you can see, the value “cho” was wrong and have reported error on name
Step out : Press “shift + f11” to jump on next breakpoint , if haven’t have any break point , program will end the debug process
