Study Notes

Language Processing System

A loader is a part of the operating system responsible for loading executable files into memory and executing them.
A cross-compiler is a compiler that runs on one platform (A) and generates executable code for another platform (B).
A source-to-source compiler translates source code from one programming language to another.

Object-Oriented Programming

Objects are the basic run-time entities in an object-oriented system.
A class is a group of objects that share common properties and program parts.
Encapsulation is the wrapping of data and functions together as a single unit.
Abstraction represents essential features without including background details.
Inheritance is a mechanism where one class can inherit properties of another.
Polymorphism means the ability to take more than one form.
Dynamic binding is when code associated with a procedure call is not known until runtime.

Compiler and Assembler

A preprocessor produces input for compilers.
An interpreter translates high-level language into low-level machine language.
An assembler translates assembly language programs into machine code.
A linker links and merges object files to make an executable file.

C# Programming Language

C# is a modern, general-purpose, object-oriented programming language developed by Microsoft.
C# is designed for the Common Language Infrastructure (CLI) and the .NET Framework.
C# supports various types, including value types, reference types, object types, dynamic types, and string types.
Pointers in C# store the memory address of another type.

Class and Object

A class is a blueprint for an object, and an object is an instance of a class.
Class and object are the basic concepts of object-oriented programming.
Modifiers can be used to specify access levels for classes and members (public, internal, etc.).

Class Declaration

The class keyword is used to declare a class.
The class identifier (or name) should begin with an initial capital letter.
A class can implement multiple interfaces.

Inheritance

Inheritance is a fundamental concept in object-oriented programming that allows defining a new class based on an existing class.
There are four types of inheritance: single, multi-level, hierarchical, and multiple inheritance.
Advantages of inheritance include code reusability, code maintenance, and code organization.
Disadvantages of inheritance include tight coupling, complexity, and fragility.

Encapsulation

Encapsulation is a mechanism that improves code reusability, usability, and testability.
Data abstraction is the process of identifying only the required characteristics of an object, ignoring irrelevant details.
Advantages of encapsulation include data hiding, increased flexibility, and easy testing.
