Procedural programming is a programming paradigm, derived from structured programming, based on 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. Any given procedure might be called at any point during a program's execution, including by other procedures or itself.
Structured programming is a programming paradigm aimed at improving the clarity, quality, and development time of a computer program by making extensive use of the structured control flow constructs of selection (if/then/else) and repetition (while and for), block structures, and subroutines.
Both of those definition are similar. I can't find a difference between the two definitions.
Both of them have:
- procedures that can be called.
- control structure, to alter control flow
Is it enough to base their difference on: procedural can call other functions within a function including itself while structured can only call a function from the main function?
What exactly differentiates these two paradigms?
