Very useful if you play games that have scripting support as mentioned.
I've heard it's also relatively easy to implement in your own projects to provide scripting support as well.

Just be aware that tables (not arrays) are 1-indexed.

I've been reading sicp and I closed the book when nothing made sense and square roots started being mentioned. Is this normal?

I am creating a recipe database which takes in ingredients as an input from the user, and outputs recipes based one those ingredients. I am using Visual Studio, C# and SQLClient. I have an SQL query which retrieves recipes that contains at least on of the ingredients, but I need it to return a recipe when ALL ingredients are in that recipe. Does anyone have any ideas how to do this?

Anyone here know SSE?

Yes. You need an IQ above 80 to understand SICP.

I'm finishing a degree in mathematics and I would like to study theoretical computer "science". Which language can other researcher expect you to know? I already know C (procedural and system), scheme (SICP) and python. Should I learn OOP?
I literally just want to apply for a master in theoretical computer science. I also plan to read CLRS (with the exercises of course). Should I also learn Haskell? It seems to be a popular language among research.

Embed a good language instead, like scheme.

If i learn ruby on rails concepts , how interchangeable are they with normal ruby ?

Let's say I want my C program to read commands with possible arguments from stdin, typed by the user during execution. Is there a better way of doing this than getting line from stdin with getline() and then using getopt on it?

I can imagine boredom and being skilled enough to do it. Most jobs (CRUD) are not interesting at all.

can you give me a sample output of that query

Please tell me of some youtube series, sites, or books I can use to learn C. I've been using this but I'm lost now that i'm at ptrs and arrays.

C Primer Plus by Stephen Prata. I use this to learn C and it's really comfy, easy to understand, everything is clear and there are many question review and exercises to review what you learned. You also learn the modern standard instead of the old way of doing things.

I wouldn't, because they always appear "on sale" so I can't take them seriously

just to clarify, that's a torrent for that udemy course.
Still, a book would most likely be a lot better. Make sure to do all exercises if a book has them

Here I just entered 'Eggs', and it outputs both Pancakes and Ommlette, yet both of these recipes include more ingredients than Eggs.

I would just take CS50 instead, it's free and by harvard, not some medium blogger.

I'm not a cs type. I like building shit and working with my hands which is why I'm a mechE. I have no fucking idea if udemy is a meme or not.

Thanks user. I find I learn best though if I use multiple sources watching a lecture, then reading the book.

reminder that this is valid c++
template
void foo(Ts......);

So if C isnt really a total subset of C++, what are some of those things that C has the C++ doesn't?

more autistic community

Its prepAration time not prepEration time

if you remove the GROUP BY clause, does it show every recipe multiple times for every ingredient that's in it? If yes, you could remove the group by and put a HAVING clause with COUNT(DISTINCT Ingredient_ID) = numOfIngredients

Designated initializers (as of C++20: more powerful designated initalizers).
Implicit conversions from void*.
There are also things that behave differently, such as inline.

I need a data structure in C++ that allows me to store a pair of objects without allowing duplicates. For example, something like an pair where first 1 and second 2 would be the same as first 2 and second 1. Does such a thing exist?

Yes it does, I tried using what you said and now I get this error:

I'm retarded, you need group by for the HAVING clause
try enabling it, but I forgot how it works then with what you've added
fuck I wish I can try it myself instead

How can I simplify chains of if statement guards on c#? I have about 120 places where I have to write
if(foo(...))
return result1;

if(bar(...))
return result 2;

...

return uniqueResult;

It's about 5 ifs each time, the parameters to foo and bar are different each time, but the result1, result2,... Are constants, except for resultUnique,which is different each time.

I think if your functions mutate state and order matters, then you can only obfuscate it.

But why? Winforms is dead.

How do I shrink a JPEG to target file size? Say it's originally 3 MB, I need it to maintain as much quality as possible and be under 1 MB. Is it as simple as just shrinking the resolution by 1/3?

That’s sepples not c.

Still no luck :( It does not make any difference from what I can see, 'Eggs' still displays both results, I also tried adding ingredients while incrementing the number of ingredients and it made no difference

Make foo return result1 or null instead of true and false, then use
return foo(...)
?? bar(...)
?? gar(...)
?? Other

Switch case and an inlined or not function that evaluates for the condition. They're all related, you know what you're doing, just name it.

>Winforms is dead.

Couldn't be further from the truth.

I don't know anything about C# but this looks to me like you either have 5 completely different conditions to break out of the function in which case I guess it is what it is and there is no simplifying to do. Maybe you can try making a high order that receives those functions and doing a switch case in there. It's the same but a bit more elegant, and maybe you can reuse this function in the 120 places you have this pattern.

Can you tell me what it does?
