What is programming language?

• A programming language is a set of rules and symbols used to write instructions that a computer can understand and execute.
• These languages allow programmers to communicate with the computer to perform specific tasks.
• This source code is written in one or more programming languages, which are used to communicate with a computer and instruct it to perform specific tasks.

Types of programming languages

Programming languages can be categorized into several types based on their features and applications. some of the important types:

1.High-Level Languages: These are user-friendly languages that are easy to read and write. They are closer to human language and abstract away most of the hardware details.

• Examples: Python, Java, C++, etc.

2.Low-Level Languages: These are closer to machine language and provide more control over hardware.

• Examples: Assembly language, Machine code

3.Procedural Languages: These languages follow a set of instructions step by step, often using loops and conditionals to control the flow.

• Examples: C, Fortran, Pascal

4.Object-Oriented Languages: These languages are based on the concept of “objects,” which can contain data and code to manipulate that data. They promote code reuse and modularity.

• Examples: Java, C++, Python, etc.

5.Scripting Languages: These languages are typically used for automating tasks, writing small programs, and enhancing web pages.

• Examples: JavaScript, Python, PHP, Perl, Ruby

Most used programming languages

1. Python: Known for its simplicity and readability, Python is widely used in web development, data science, artificial intelligence, scientific computing, and automation.
2. JavaScript: The backbone of web development, JavaScript is essential for creating interactive websites and is used alongside HTML and CSS. It also has a strong presence in server-side development with Node.js.
3. Java: A versatile, object-oriented language commonly used for building enterprise-scale applications, Android app development, and large systems.
4. C++: An extension of C, C++ is used for system/software development, game development, real-time simulations, and performance-critical applications.

Why we use C++ for DSA?

We use C++ for Data Structures and Algorithms (DSA) because…

1. Performance: Provides high efficiency and fast execution.
2. Efficiency: The lines of code are small.
3. Memory Management: Allows direct manipulation of memory.
4. Problem solving: process of identifying a challenge and finding effective solutions to address it.
5. Object-Oriented Features: Supports modular and reusable code.
6. Low-Level Manipulation: Enables fine control over data and resources.
7. Portability: Code can run on various platforms with minimal changes.

Where do we use the C++ language?

C++ is used in various domains and applications due to its versatility, performance, and efficiency. Some common areas where C++ is used are:

• System Software Development
• Game Development
• Embedded Systems
• GUI Applications (Graphical User Interface)
• Database Management Systems (DBMS)
• Web Browsers
