Procedural or Procedure Oriented Programming (POP)
As the name implies, Procedure Oriented Programming contains step by step procedure to execute. Here, the problems get decomposed into small parts and then to solve each part one or more functions are used. Thus, in POP approach, the problem is viewed as a sequence of things to be done, such as, input taking, calculating and displaying. The primary focus stays on functions which will be used to accomplish each task.
