Object Oriented Programming C++

Structured programming (sometimes known as modular programming) is a subset of procedural programming that enforces a logical structure in the programming 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 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. Program flow follows a simple hierarchical model that employs looping constructs such as “for”, “repeat” and “while”. Use of the “Go To” statement is discouraged. Structured programming was first suggested by Corrado Bohm and Guiseppe Jacopini. The two mathematicians demonstrated that any computer program can be written with just three structures: decision, sequences, and loops. Coders should break larger pieces of code into shorter subroutines (functions, procedures, methods, blocks, or otherwise) that are small enough to be understood easily. In general, programs should use local variables and take arguments by either value or reference. These techniques help to make isolated small pieces of code easier to understand the whole program at once. PASCAL, Ada, C, are some of the examples of structured programming languages.
