What is the primary difference between imperative and declarative languages?
Imperative languages specify how to solve a problem, while declarative languages specify what needs to be done, without telling how to do it.
What is the main focus of structural programming?
What is the main focus of structural programming?

Study Notes
Programming Paradigm Overview
- A programming paradigm is a set of related concepts and different approaches to programming.
- Each paradigm has its own pros and cons, but ultimately, they should be able to solve the same problems, just in different ways.
- Experience in multiple paradigms is beneficial, and many programming languages are multi-paradigm, supporting different approaches.
Imperative and Declarative Languages
- Imperative languages have explicit commands, specifying how to solve a problem.
- Declarative languages specify what needs to be done, without telling how to do it.
- Declarative languages, like SQL, express the desired endpoint, and let the compiler or engine figure out how to achieve it.
Imperative Paradigms
- Structural Programming: emphasizes clear, organized code, with abstracting, parameters, and return values, and clear control flow.
- Procedural Programming: uses subroutines to carry out specific tasks on data, often using structured programming.
- Object-Oriented Programming: uses objects and classes to encapsulate behavior and data, with benefits and drawbacks.
Declarative Paradigms
- Functional Programming: expresses problems in a mathematical way, using subroutines, function calls, and recursion, to specify the desired endpoint.
- Functional programming is often used in data science and is a more niche and less commonly used paradigm.
Other Key Points
- Many programming languages lean towards a particular paradigm, but may not always be tightly defined.
- Programming as a field developed rapidly, and definitions have evolved over time.
- There are two high-level approaches: imperative and declarative languages.
- Experience in multiple paradigms can provide context and help in choosing the best approach for a particular problem.

Imperative Paradigms
Structural Programming
- Emphasizes clear, organized code with abstraction, parameters, and return values.
- prioritizes clear control flow.
Procedural Programming
- Uses subroutines to perform specific tasks on data.
- Often uses structured programming techniques.
Object-Oriented Programming
- Uses objects and classes to encapsulate behavior and data.
- Has benefits and drawbacks.
Declarative Paradigms
Functional Programming
- Expresses problems in a mathematical way.
- Uses subroutines, function calls, and recursion to specify the desired endpoint.
- Often used in data science, and is a niche paradigm.
Other Key Points
- Many languages lean towards a particular paradigm, but may not be strictly defined.
- Programming has evolved rapidly, and definitions have changed over time.
- There are two high-level approaches: imperative and declarative languages.
- Experience in multiple paradigms provides context and helps choose the best approach for a problem.
