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 (not to be confused with mathematical functions, but similar to those used in functional programming), 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. Procedural programming languages include C, Go, Fortran, Pascal, and BASIC. == Procedures and modularity == (詳細はModularity is generally desirable, especially in large, complicated programs. Inputs are usually specified syntactically in the form of ''arguments'' and the outputs delivered as ''return values''. Scoping is another technique that helps keep procedures modular. It prevents the procedure from accessing the variables of other procedures (and vice versa), including previous instances of itself, without explicit authorization. Less modular procedures, often used in small or quickly written programs, tend to interact with a large number of variables in the execution environment, which other procedures might also modify. Because of the ability to specify a simple interface, to be self-contained, and to be reused, procedures are a convenient vehicle for making pieces of code written by different people or different groups, including through programming libraries. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Procedural programming」の詳細全文を読む スポンサード リンク
