I want to understand how to properly nest key/pair values within a struct. My use case is to create a type to return serialized JSON on my API responses.
I'm using rocket, this is my general setup:

name = "api"
version = "0.1.0"
edition = "2018"

I made this quiz but the code seems to be really lengthy. Can anyone find a way to make my code shorter? Considerably shorter would be best but anything helps. I think the main problem is the repeating of the questions.

Well, I'm writing a piece of code that will take a list of file names and should search a local drive for each file, determine if it's there or not, and return an array of all the paths found.
Right now I'm using a function that searches for one file and I call this function for each file in the list:

I'm currently implementing an interner in the style of Guava's Interner, where:
an intern pool is maintained for an immutable class
whenever a new instance of that class is created, it's checked to see if it's equal to an existing instance in the intern pool
if such an existing instance is found, it's returned, otherw... | stackexchange/codereview |
There is a Name class with properties that represent different components that make up a person's name. A Name object requires a FirstName and Surname. All other fields are optional.

Took me a couple of days (in between working on other projects) to get the code working, but now that I do have it working I would like to know if there is a way that I could make it work better, or clean up my act JavaScript/jQuery surrounding my JSON utilization skills.

I am a beginner who wrote this simple Hangman game in C for fun and to practice programming. I am looking for advice on optimizing this code and making it adhere to best practices. Are there too many variables, conditionals, and loops?

I decided to try out Python (3.x) two or so weeks ago, and this is my first real script using it. The program I've written below is slow, clunky, inefficient, inaccurate, and probably poorly coded! But it produces what I want most of the time, and it was really just a project to become accustomed to different Python te... | stackexchange/codereview |
I have two Pandas DataFrames and I want to subset df_all based on the values within to_keep. Unfortunately this isn't straight forward pd.merge() or df.join() because I have multiple columns that I want to match on, and I don't care what order the match happens.
I don't care if df_all['source'] matches in either to_k... | stackexchange/codereview |
I have to implement an image-Carousel.
Because I'll reuse the snippet within other projects which might contain all kinds of external libraries I used an immediately invoked function expression.
Could my code be improved?
All Hints appreciated.
