Clasification
Programming lanuages are divided into 3 maintypes: Assembly language,
Machine laguage, high-level language
Assembly language, also known as low-level language, is not commonly used by programmers It uses English words for programming and development, for example "Input" for input, "Output" for output, and "add" for addition.
- This type of language is not easily accessible for many programmers, but if you have a good understanding of its structure and characteristics, your programming tasks will become simpler and more efficient.
- When first introduced, Assembly language was used in many programming aspects, but with the development of the industry today, it is only used in certain fields It is only considered for use in supporting communication between hardware or serving high-speed processing issues.
- For those who are familiar with Assembly language, they consider it to be a very computer-friendly language Programs written in this language have the ability to run quickly and do not consume much memory space.
- Assembly language is widely used in writing the kernel of operating systems and creating games
- Machine language, also known as machine code, is the language directly executed by the computer's central processing unit (CPU) It is considered the lowest level language, and is composed of binary digits 0 and 1.
- This type of language is not used by human programmers, as it is difficult to read and write Instead, machine language is used to program the underlying architecture of computers.
- Despite the difficulty of using machine language, it provides the most direct and efficient communication with the computer, as it is the only language the computer can understand.
High-level languages are easier to use than low-level languages, as they use a more human-friendly syntax and vocabulary Some popular examples of high- level languages include C++, Python, Java, and Ruby.
- These languages are used by most programmers, as they allow for rapid prototyping and development of complex software systems High-level languages are also easier to debug and maintain, as they are closer to human language and can be easily understood by other programmers.
- High-level languages are designed to be portable, meaning they can be run on different computer systems without requiring modification This makes them ideal for developing large and complex software systems that need to run on multiple platforms.
Current programming language
C and C++ are programming languages that have been widely used for several decades They are known for their efficiency and performance and are used to develop a wide range of applications, including operating systems, device drivers, and embedded systems.
C was developed by Dennis Ritchie at Bell Labs in the 1970s and was designed to be a general-purpose, high-level programming language that could be used for a variety of applications The development of C was influenced by several other programming languages, including BCPL and B, and was designed to be a simple, efficient, and low-level language.
C++ was developed by Bjarne Stroustrup at Bell Labs in the early 1980s as an extension to C The development of C++ was motivated by the need for a language that would allow for object-oriented programming and make it easier for developers to create large-scale, complex software systems C++ incorporates features from other object-oriented programming languages, such as Simula, and was designed to be compatible with C, so that existing C programs could be easily converted to C++.
C and C++ have evolved over the years, and several new features have been added to both languages, including support for generic programming, exception handling, and templates Despite the addition of new features, both languages have remained largely backwards-compatible, so that existing code written in C and C++ can continue to be used with modern compilers.
• Low-level memory access: C and C++ allow direct manipulation of memory through pointers, which is useful for tasks such as allocating memory dynamically, working with hardware, and creating efficient algorithms.
• Compiler-based: Both C and C++ are compiled languages, meaning that source code is transformed into machine-readable code by a compiler, rather than interpreted at runtime.
• C-style syntax: C++ extends C with several new features, but retains the syntax and basic structure of C, making it easy for C programmers to learn.
• Object-Oriented Programming (OOP) Support: C++ adds support for OOP concepts like classes, inheritance, polymorphism, and encapsulation, making it possible to build complex, modular applications.
• Standard Template Library (STL): C++ provides a rich set of standard libraries, including the STL, which is a collection of generic containers, algorithms, and iterators for common programming tasks.
• Platform independence: C++ programs can be written once and run on multiple platforms, which is useful for cross-platform development.
• Large community and rich resources: C and C++ have been widely used for many decades, which means that there is a large community of users and a wealth of resources available to help you learn and use these languages effectively
The use of C and C++ has been essential to the growth and development of the tech industry due to their performance, efficiency, and ability to create highly optimized code It can be devided into several categories:
• System Programming: C and C++ are widely used for system programming, which involves developing low-level software components that interact with the underlying operating system or hardware Examples of system programming applications include operating systems, device drivers, and embedded systems.
• Game Development: C++ is widely used for game development due to its performance and ability to create highly optimized, low-level code Many popular game engines, such as Unreal Engine and Unity, are written in C++.
• Software Development: C and C++ are widely used for developing a wide range of applications, including desktop applications, mobile apps, and scientific applications.
• Web Development: C++ is not commonly used for web development, although some web servers, such as Apache, are written in C.
• Education: C and C++ are widely taught in universities and are an important part of the computer science curriculum They are often used as introductory languages for students because they are simple to learn and provide a solid foundation for learning other programming languages.
Java was developed by James Gosling and his team at Sun Microsystems (now owned by Oracle Corporation) in the mid-1990s The development of Java was motivated by the need for a portable and secure programming language that could be used for a variety of applications, including embedded systems, web applications, and mobile applications.
One of the key goals of the Java development team was to create a language that was "write once, run anywhere" (WORA), meaning that Java code could be written once and then run on any device that had a Java Virtual Machine (JVM) installed, regardless of the underlying hardware and operating system This was achieved by designing Java to be portable and secure, and by developing the JVM, which interprets Java code and executes it on the target platform.
Object-Oriented: Java is designed with object-oriented programming concepts, such as classes, objects, inheritance, and polymorphism, making it possible to create complex, modular applications.
Platform Independent: Java is platform-independent, meaning that code written in Java can run on any device with a Java Virtual Machine (JVM) installed, without the need for recompilation.
Memory Management: Java has automatic memory management, meaning that the programmer does not have to worry about freeing up memory that is no longer needed The Java Virtual Machine (JVM) takes care of this automatically.
Rich Standard Library: Java has a rich set of standard libraries for tasks such as input/output, networking, and database access, making it easier to develop applications.
Multi-Threading: Java has built-in support for multi-threading, which makes it easy to write programs that can run multiple tasks concurrently.
Secure: Java is designed with security in mind, with features such as type-checking, automatic memory management, and a security manager that enforces access restrictions.
Portable: Java applications can run on any device that has a Java
Virtual Machine installed, without the need for modification or recompilation.
Easy to learn and use: Java has a clean, readable syntax, and the language is designed to be easy to learn and use, making it a popular choice for beginning programmers and experienced developers alike.
Java was first released to the public in 1996, and since then, it has become one of the most widely used programming languages in the world Java is widely used for a variety of applications, including:
