What are the 4 types of coding?

The "4 types of coding" usually refer to programming paradigms: Imperative, focusing on how to do something (like Procedural); Declarative, focusing on what to achieve (like Functional or Logic); and Object-Oriented, organizing code around objects; while sometimes a fourth is cited as Scripting, for automation, though categories overlap.
 

Is C better than Python?

Ease of development – Python has fewer keywords and more free English language syntax whereas C is more difficult to write. Hence, if you want an easy development process go for Python. Performance – Python is slower than C as it takes significant CPU time for interpretation. So, speed-wise C is a better option.

Is CS the hardest degree?
