A third-generation programming language (3GL) is a high-level programming language that is closer to human language and provides more abstraction from machine-level details compared to lower-level languages like assembly language. Here are some key characteristics and features of third-generation programming languages:

  1. Abstraction: 3GLs provide higher levels of abstraction, allowing programmers to focus more on problem-solving rather than machine-specific details. They use statements and expressions that are closer to natural language and are easier to understand and maintain.
  2. Procedural Programming: 3GLs support procedural programming paradigms, where programs are structured into reusable procedures or functions. This allows for modular and organized code, making it easier to develop and maintain complex applications.
  3. Data Structures: 3GLs provide built-in support for complex data structures like arrays, records, and structures. This enables programmers to work with collections of data and organize information in a meaningful way.
  4. Control Flow: 3GLs offer various control structures such as loops (for, while), conditional statements (if-else, switch), and branching (goto). These structures control the flow of program execution and allow for making decisions based on conditions.
  5. Portability: 3GLs are designed to be platform-independent, meaning that programs written in these languages can be executed on different hardware and operating systems with minimal modifications.
  6. Examples: Examples of popular third-generation programming languages include C, C++, Java, Python, Fortran, and Pascal. These languages are widely used in various domains, including software development, scientific computing, web development, and more.

Overall, third-generation programming languages provide higher-level abstractions, more structured programming capabilities, and better code readability compared to lower-level languages. They allow developers to write efficient and maintainable code by focusing on the problem-solving aspect rather than dealing with low-level machine details.
