Structured Programming

Structured programming is a procedure oriented method of designing and coding a program, it is just a subset of procedural programming that enforces a logical structure on the program being written to make it more efficient and easier to understand and modify.

Structured programming frequently employs a top-down design model, in which developers map out the overall program structure into separate subsections. A defined function or set of similar functions is coded in a separate module or sub module, which means that code, can be loaded into memory more efficiently and that modules can be reused in other programs. After a module has been tested individually, it is then integrated with other modules into the overall program structure.

Use of the “Go To” statement is discouraged in structured programming. Some of the better known structured programming languages are Pascal, PL/I, and Ada.
