The unit in procedural programming is function, and unit in objectoriented programming is class. Functional vs objectoriented vs procedural programming.
Software development has really come a long way over the past few decades. So basically structured code where functions or procedures dominate over data is called procedural whereas class and object based representation is called object oriented. One useful exercise may be to compare and contrast objectoriented programming to more traditional structured programming. However, languages such as c introduced syntax specific to these coding styles to make. Procedural programming language vs structured programming language. In this approach, procedures are calledexecuted only in response to events, which may include mouse clicks, keyboard press, attaching or removing a device, arrival of data from an external source, etc. Structured programming sometimes known as modular programming is 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 approach with advantages and. They put forth the ideas of defining levels of abstraction and the definition of. Since the programming is stepbystep, in a really long program it becomes tough to back and follow up on the developments. It doesnt support the possibility of jumping from one instruction to some other with the help of any statement like goto, etc.
Whats the difference between imperative, procedural and structured programming. In procedural programming the data is not the focus and would not be introduced until needed in the program. What is procedural and object oriented programming. Assembly language can support procedural or structured programming via its facilities for modifying register values and branching execution depending on program state. Basic concept of object oriented and procedure oriented. Trends in programming, evident in global software companies, have necessitated the integration of object oriented programming oop paradigm into computer science programming courses.
