How to use append-map in Racket (Scheme)

阅读更多关于 How to use append-map in Racket (Scheme)

问题 I don't fully understand what the append-map command does in racket, nor do I understand how to use it and I'm having a pretty hard time finding some decently understandable documentation online for it. Could someone possibly demonstrate what exactly the command does and how it works? 回答1: The append-map procedure is useful for creating a single list out of a list of sublists after applying a procedure to each sublist. In other words, this code: (append-map proc lst) ... Is semantically

问题 I visited so many sites about the differences between Procedular Oriented Programming and Object Oriented Programming , but I did not get Practical answer . Everyone is saying theoritical answer . Can anyone give Practical Explanation for this ? 回答1: Procedural programming is a list or set of instructions telling a computer what to do step by step and how to perform from the first code to the second code. the best example of a procedural language is C for e.g here is a python code for

阅读更多关于 What GUI libraries are not object-oriented? [closed]

I have been using C a lot lately, and want to explore programming more than just console applications. However, most GUI libraries are object-oriented, and it is very difficult to program with them in programming languages which are not object-oriented such as C. Even object-oriented GUI libraries such as GTK+ that are designed for C require a lot of boilerplate. Because I am having difficulty with these object-oriented libraries I am wondering what GUI libraries are not object-oriented? I don't know of any modern GUI toolkit that isn't object oriented. OO is simply a very useful programming

How do i get out of the habit of procedural programming and into object oriented programming?

阅读更多关于 How do i get out of the habit of procedural programming and into object oriented programming?

问题 I'm hoping to get some tips to kinda help me break out of what i consider after all these years a bad habit of procedural programming. Every time i attempt to do a project in OOP i end up eventually reverting to procedural. I guess i'm not completely convinced with OOP (even though i think i've heard everything good about it!). So i guess any good practical examples of common programming tasks that i often carry out such as user authentication/management, data parsing, CMS/Blogging/eComs are

Development Cost of Procedural Programming vs. OOP?

问题 I come from a fairly strong OO background, the benefits of OOD & OOP are second nature to me, but recently I've found myself in a development shop tied to a procedural programming habits. The implementation language has some OOP features, they are not used in optimal ways. Update: everyone seems to have an opinion about this topic, as do I, but the question was: Have there been any good comparative studies contrasting the cost of software development using procedural programming languages

Closed . This question needs to be more focused. It is not currently accepting answers. Learn more . Want to improve this question? Update the question so it focuses on one problem only by editing this post . I still don't understand the difference after reading this So, rather than asking what is the difference between functional vs procedural programming, I thought, maybe a language that I am familiar with can serve as an example. Hence, my questions: Are the languages R/SAS considered procedural or functional? R is primarily a functional programming language. It does have some exceptions

Does procedural programming have any advantages over OOP?

阅读更多关于 Does procedural programming have any advantages over OOP?

问题 [Edit:] Earlier I asked this as a perhaps poorly-framed question about when to use OOP versus when to use procedural programming - some responses implied I was asking for help understanding OOP. On the contrary, I have used OOP a lot but want to know when to use a procedural approach. Judging by the responses, I take it that there is a fairly strong consensus that OOP is usually a better all-round approach but that a procedural language should be used if the OOP architecture will not provide
