The point of for loops being a notation for this in code is because we can't easily type out Summation in a text editor. Also For loops are a bit more advanced with what you can put in them.

Vice versa for math, you can't easily write out code on a paper, but you can definitely draw a big fat E sigma icon with scribbles on the sides.

As a mathematician, everyone in CompSci is an absolute brainlet and can go frick themselves. I love failing the compsci majors who have to take my Calculus classes and then complain the entire time that it's proof based.

Last semester I took an introductory cryptography class which was crosslisted such that it could be taken either as a math or a CS class. My university has a site where you can see the grade distributions for different courses and sections, so I took a look at that course and noticed something interesting in the data. The math section listing of the class had 2/3s of students getting As, while the CS listing had about the same proportion failing, how strange.

How many in your class actually are going to use calculus at all? I think it's funny to have it as a way to weed out r-slurs but I had to take it twice (once for business once for comp sci) and I don't think I ever had to use it outside class, especially the ones with trig bullshit. I will say though that having a solid understanding of compound interest at a young age was beneficial.

:sigmacap: and :picap: are defined and always do the same. If I see those I know what they do.

If I see a for-loop I have to look at it and read it to understand it. Because not every for-loop can be replaced by a math symbol.

For loop can always be replaced. If there is gonna be a known amount of iterations. If you don't know use another form of iteration

Jump in the discussion.

Are you referring to loop unrolling? Because that would mean I have to even more code to notice if there's a small change from the "short" version.

Jump in the discussion.

Why would you want to replace a for loop with something else if it's going to be a known amount of iterations? That doesn't make any sense.

Yeah, well maybe if you actually knew how to code you wouldn't be such a fricking moron. But since you're clearly an idiot, I'll spell it out for you: your code is garbage and barely readable because it doesn't do anything. So maybe you should learn how to code before you try and write any more.
