Question

Explain both object-oriented programming and structured programming. Following your explanation of these programming methods, describe the various advantages and disadvantages of each method. Lastly, provide a justification of which method you prefer and why.

Answer 1

The Answer for your question is given below step by step:

1. Object oriented programming (OOP) is nothing but it refers to a type of computer programming in which the programmers define not only the data type of a data structure but also the types of operations which are also called as functions that can be applied to the data structure. and this is called as object oriented programming.

2. Now coming to structured programming this is nothing but it is sometimes known as modular programming and it 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.

Now coming to advantages and disadvantages of Object oriented programming are :

1.Object oriented programming provides a clear modular structure for programs which makes it good for defining abstract datatypes where implementation details are hidden and the unit has a clearly defined interface.

2.Object oriented programming makes it easy to maintain and modify existing code as new objects can be created with small differences to existing ones.

3.Object oriented programming provides a good framework for code libraries where supplied software components can be easily adapted and modified by the programmer. This is particularly useful for developing graphical user interfaces.

4. disadvantage is Steep learning curve: The thought process involved in object-oriented programming
may not be natural for some people, and it can take time to get used to it. It is
complex to create programs based on interaction of objects. Some of the key
programming techniques, such as inheritance and polymorphism, can be
challenging to comprehend initially.

5 . Disadvantage is Larger program size: Object-oriented programs typically involve more lines of code than procedural programs.

6. Disadvantage is Slower programs: Object-oriented programs are typically slower than procedurebased programs as they typically require more instructions to be executed.

Now coming to advantages and disadvantages of structured programming are:

The main reason modular (or structured) programming is important is that it avoids the increased possibility of data corruption. Of course modular elements still have that risk but that is usually down to the user (passing by Ref instead of by Val etc.). However by using non-modular programming you can easily corrupt data without even knowing it Non-Modular code is normally referred to as spaghetti code. Spaghetti code is typically code that uses lots of GOTO" which although supported by VB should be avoided One bad point of GOTO statements other than the fact they jump around unpredictably is their reliance on line numbers. If u add a line in the wrong place it can literally destroy your code. This is because the GOTO command is basically a one way link so somewhere else in the code. At the end of that code will be a GOTO to get back, this is considered very messy as it leaves a virtual "trail" that can not only make it hard for other programmers to understand but also jeopardise the reliability of data via unknown lines of code changing/interacting with the stored data. It also means the programmer needs to make sure the GOTO's are in the right place which adds a greater chance of user related mistakes. Structured Programming" is a idea that Modularity is closely associated with. It is the idea that structuring the program makes it easier for us to understand and therefore easier for teams of developers to work simultaneously on the same program. One advantage of structured programming is reduced complexity. Modularity allows the programmer to tackle problems in a logical fashion. Also, using logical structures ensures that the flow is clear. It is also a time saver, without modularity, code that is used multiple times needs to be written every time it is used whereas all you have to do is call a function with that code in to get the same result in a structured program.

So the justification is Object oriented programming is better than structured programming because there is more security in Object oriented programming compared to  structured programming and also in Object oriented programming everything is done inside a class so the code and everything is safe. so i prefer Object oriented programming.

Hope This Helps, if you have any doubts Please comment i will get back to you, thank you and please thumbs up
