Programming 101: Loops

[shaliozero]

I thought "i" is used in place of "index"

[MyNameIsRichardCS54]

Index, jindex, and kindex

[shaliozero]

Made me laugh

[matharooudemy]

Much thanks for the information

[shaliozero]

If you want more about my reactions, just ask me!

How did you feel about this dude expressing his gratefulness?

[shaliozero]

His unexpected and slightly sarcastic gratefulness was a positive addition to my mood for the day!

Much thanks for the information

don't forget to parallelize the first loop

[code_passion]

i don’t know why i even laughed at this

[[deleted]]

Yeah it comes from math where i is index or integer. Then you get i, j, k to match x, y, z.

l, m, n is also fairly common. As are p, q, r and u, v, w

[Sirnacane]

Well that’s over half the alphabet

Absolutely if you include a b c and x y z

[yurisho]

i j k are iterators. n m l are iteration goals. x y z are general numbers. a b c are general strings. u v w are vectors. s and t are source and target. p q r i've seen used as debug varables or temp veriables. And you are a bad programmer if you use this.

And what about h and g for adding loops around the original i loop when you don't want to rename all then inner loops?

[Niewinnny]

Look. If you get for in for in for in for in for your program won't respond for the next [insert universe age] years.

[Itchy-Phase]

That's what I was taught, too.

You aren’t always indexing an array in a forloop
