What are the uses of procedural programming?

Answer 1

Procedural programming language involves coding instructions that a computer executes in a particular order. The language makes it easy to debug different procedures in isolation. It is also easy to read the code hence making it easy to change a particular procedure. The disadvantages include the need to change large portions of the code during porting and inability to use the original code on a different application.

Answer 2

Well if you are creating a large program with many parts to it then procedural programming languages simply dont fit the bill, this is because the code becomes messy. It becomes messy because you cant write your code in a modular format and therefore your source code will look like an endless list of procedures where as with a non-procedural language such as OOP(object oriented programming) you can split your code into objects or functional parts that interact and can be viewed and edited in isolation. This means when you are drawing up the plan to create your program your code will follow the same format.

Answer 3

Non-procedural languages (declarative languages) specify what is to be solved, as opposed to procedural languages (imperative languages) which specify how to solve the problem. Declarative languages include functional and logical languages such as Lisp and Haskell, while imperative languages include structured and object oriented languages such as C, C++ and Java. Some languages are both imperative and procedural, such as Prolog and SQL.

Declarative languages do not alter the machine's state and therefore have no side-effects. Imperative languages always have side-effects.

HTML is a typical example of non-procedural programming. With HTML we can specify what is to be rendered but we cannot dictate how it is rendered nor can we interact with the user. For those aspects we need to use client-side scripts which are supported by HTML but are not actually part of the language itself; scripts are languages in their own right.
