Short answer

C. Third

Step-by-step solution

Understanding Generations of Programming

Programming languages evolved in generations, each introducing new concepts and advancements. First-generation refers to machine code, second to assembly languages, third to high-level languages like FORTRAN and COBOL, fourth to very high-level languages like SQL, and fifth to artificial intelligence languages.

Defining Structured Programming

Structured programming is a programming paradigm aimed at improving clarity, quality, and development time by using the structured control flow constructs of sequence, selection, and iteration. It became popular in the development of third-generation languages.

Matching to the Correct Generation

Structured programming is closely associated with third-generation languages, which are high-level procedural programming languages. This era focused on producing more readable and maintainable code.

Key concepts

Structured Programming

Structured programming is a programming method designed to improve the organization and clarity of code. It simplifies the development process by using a straightforward approach, breaking down a program into manageable sections called modules. Similar to building blocks, these modules use three core constructs for controlling the flow of the program: sequence, selection, and iteration. Each module is designed to perform a single task, making the program easier to read and maintain.

• Sequence: running lines of code one after another.
• Selection: making decisions using statements like if-else.
• Iteration: looping with structures like for and while.

Structured programming gained popularity with third-generation languages due to their ability to simplify code and improve program efficiency.

Third-Generation Languages

Third-generation languages (3GLs) marked a significant shift from the previous generations of programming languages. They introduced a higher level of abstraction compared to first and second-generation languages, which involved working directly with machine or assembly language. These languages, like FORTRAN and COBOL, allowed programmers to write in a more human-readable syntax, making it easier to write, debug, and maintain code.
Key features of 3GLs included:

• Procedural programming: Focusing on procedure or routine sequences for clear, logical code flow.
• Machine independence: Code written in 3GLs could be compiled and run on any machine with the proper compiler.
• Enhanced readability: Using English-like syntax improved understanding.

These languages laid the groundwork for advancements in software development and became the foundation for structured programming.

High-Level Languages

High-level languages (HLLs) are programming languages that wisely abstract the details of the computer's hardware. This abstraction allows programmers to focus on coding algorithms without worrying about intricate hardware details. High-level languages simplify the programming process, making programming accessible to more people by using familiar syntax and semantics.
Benefits of using HLLs:

• Increased productivity: Developers can write more functional code in less time.
• Portability: Programs can be easily adapted to different hardware configurations.
• Easier problem-solving: Abstracts hardware complexities.

Examples include languages like Python, Java, and C++. Each offers robust functionality while being straightforward to use.

Programming Paradigms

Programming paradigms are fundamental styles or approaches to programming, dictating how solutions to problems are structured. They influence the way programmers process information and solve computing problems. Different paradigms offer distinct methodologies, each with its own strengths for various types of projects.
Popular programming paradigms include:

• Procedural programming: Based on the concept of calling procedures or routines.
• Object-oriented programming: Organizes code around "objects," simplifying complex systems.
• Functional programming: Treats computation as the evaluation of mathematical functions.
• Logical programming: Uses facts and rules to derive solutions.

Using the right paradigm is crucial, as it directly impacts the development and performance of software applications. By understanding and applying the appropriate paradigm, developers can write more efficient and maintainable code.
