Method syntax producing error
I am learning Ruby using codecademy and the current exercise tells the user to :
Define two methods in the editor:
A greeter method that takes a single string parameter, name, and returns a string greeting that person. (Make sure to use return and don't use print or puts.)
A by_three? method that takes a single integer parameter, number, and returns true if that number is evenly divisible by three and... -
I found the answer already but thank you if you were about to post something helpful!
Code:puts "Whats your input brah?" text = gets.chomp puts "Whatchu are you hiding bro?" redact = gets.chomp words = text.split(" ") words.each {|x| if x == redact then print "REDACTED"+" " else print "#{x}"+" " end}Leave a comment:

This code definitely works if I use "do" instead of the curly braces. I tested it. The tutorial I am using said that those two are the same thing and can be used inter-changably but as I found, it doesn't work when I use curly brackets. Unless I am missing something important.Leave a comment:

printing a redacted word in an if loop
My code won't print "REDACTED" in place of the redact variable. I do not know why though. Can anyone shed some light? I appreciate it! Here is my code :

Largest element in array, variable query
Hello All,
I was curious as to why the for loop in the example below, starts col = 1 instead of col = 0. Are they doing that just for this example because the largest value is stored in column 0 (the first column)? Also, I don't understand why the inequality sign is < instead of > because I am looking at it like:
If the largest value > the current value being evaluated in a particular iteration, then the largest... -
I can't connect how "shift" is implemented in this particular program.
This is a start:
I need to map the letters 'A' through 'Z' (assuming only uppercase letters) to the integers 0 through 25.
n = c - 'A';
Now I perform the shift with modulus arithmetic:
n = (n + shift) % 26;
Finally map back to a letter:
p = n + 'A';
but can anyone...Leave a comment:

I think if I shift a character by a shift amount the character may or may not be out of bounds:
'a' + 3 is 'd' ok,
'x' + 3 is '{' not ok.
So if the character is over 'z' take away 26, if under 'a' add 26. can be a usable function.
However, can someone please explain to me how the shift is calculated in the program and is applied it to the file? It has me totally stumped :(Leave a comment:

Trouble understanding a shift calculation
Hey all!
I was going over this code to read a file on my desktop that decrypts a cesar cipher code and I am stuck trying to figure out how the shift is calculated in this program.
From what I can tell, Max e's is the shifted letter with the highest frequency. Since e's are the most common letter in English, the program is trying to set the highest frequency char in the cipher, to an 'e' in English. Which is good, as far... -
Oh, well it didn't effect my calculations in any way but you are correct of course. I overlooked that part thanks for the correctionLeave a comment:

Thanks friend! What I ended up doing was on line 16, I changed 0 to 1 because 0 is not prime. Then, I added (double) to line 70. Lastly, I made b =1. That did the trick. Thanks for the tips! I left set precision in there because it did make my columns look neater :)Leave a comment:

Prime Number chilliad program calculation adjustment?
Hi Guys!
I was wondering if someone could give me a quick tweak. I just finished my chilliad program. It calculates the primes and average number of primes. However, when I look at my answer and the teacher's answer, I seem to be off by like a smidgen.
She has:
Total primes in the first 50 chiliads: 5133
Average number per chiliad: 102.66
I have:
Total primes in the first... -
Ok, wow, thank you so much for that! You just put it into perfect perspective for me!! I appreciate it!Leave a comment:

My book wasn't clear on whether or not rand was assigned to be between 1-6 or not. So, I assumed the function had to come to 1-5(+ 1) on its own.Leave a comment:

So, does rand() % 6 know to return a value of 1-5 in the first place? 1-5 is supposed to be the result (plus one of course). I mean, 6 / 32767 = 5461.16 +1 = 5462 true, but how does this function then, take the number 5462 and spit out 1-5 (plus 1)? That is the crux of my confusion.Leave a comment:

Hi There,
Thanks for your reply! I am currently taking math95 along with CS161 so a modulus being a part of regular math is news to me. I never heard of it until mt CS161 class.
Anyway, although you pointed that out, I am still left with my original question. It sounds like you basically misunderstood it, that's not a hard thing to do considering I did a poor job trying to articulating my concern in the first place. I'll try to...Leave a comment:

Calculating the formula of a dice roll using rand?
Hi Guys!
So, I am using the modulus and a rand as part of a function I am writing. Now, I understand that:
gives me a random number between one and six in this situation. However, I also know thatCode:rand() % 6 + 1;
gives me a random value from 0 - 32767 andCode:rand();
changes the sequenceCode:srand;
but I thought...
% = Whatever the remainder of a is after a / b.
... So, if you... -
Arithmetic using a for loop
Hello Everyone,
One thing that I was not able to fully understand even though I read through the section on it a few times, is the for loop. I mean, I understand the premise of (statement, condition, update statement). However, I do not quite understand how a math problem is affected by this.
Can someone clarify with a simple example of how this works using multiplication and division? I would really appreciate it!

Ok problem solved, here is my result. It works like a charm:
