Procedural programming is a programming paradigm, derived from structured programming, based upon the concept of the procedure call. Procedures, also known as routines, subroutines, or functions, simply contain a series of computational steps to be carried out. Paradigms are simply a model, for example a pattern or way of doing something. Another type of programming paradigm that procedural programming can be contrasted with is eventdriven programming. Object oriented programming uses an object to design applications and programs.

Any given procedure might be called at any point during a programs execution, including by other procedures or itself. Procedural programming generally flows from one statement to the next, with occasional jumps and loops handled with goto statements. So, rather than asking what is the difference between functional vs procedural programming, i thought, maybe a language that i am familiar with can serve as an example.

The following are the features that will show some differences between procedural programming and object oriented programming. It is a procedural programming language in the form of a set of commands that need to be executed in a sequence like that of a batch file. Functional programming is the same except that functions are firstclass values, so they can be passed as arguments to other functions and returned as results from function calls. Proceduralabstraction of a statement allows us to introduce new operations using the name of a sequence of instructions in place of the sequence. Procedures, also known as methods, functions, routines or subroutines, simply contain a series of computantional steps to be carried out.

Procedures, also known as routines, subroutines or functions, simply consist of a series of computational steps to be carried out. Functional language functions and difference functional languages, are typically the languages that support recursion, and thus require functions to be there.
