Ruby script - HTC Rezound

I am in an introduction to programming class and have some questions on a script I am working on. Anyone familiar with the Ruby
(.rb) language. Thanks

Not really sure why this is in the Rezound QA...
I'm not familiar with Ruby (other than just looking at some code a few times)... but what's the issue you're having exactly?

lol I figured I would get that exact response, but it seemed like a good place to ask to be honest. I have this set of code here, Im not cut out for programming and was looking for help this is the pseudocode for the project I am working on.
MAXLINELENGTH = 40
codes = ['.-', '-...', '-.-.', '-..', '.', '..-.',
'--.', '....', '..', '.---', '-.-', '.-..',
'--', '-.', '---', '.--.', '--.-', '.-.',
'...', '-', '..-', '...-', '.--', '-..-',
'-.--', '--..','.----', '..---', '...--',
'....-', '.....', '-....', '--...', '---..',
'----.', '-----']
chars = "ABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890"
f1 = File.open("index.txt", "w")
f2 = File.open("index.txt", "r")
Initialize line_length = 0
while character = fin.getc
if index = chars.index(character.upcase)
code.getc
Print code to fout
Print " " to fout
line_length = line_length + code.length + 2
end
elsif character == " "
Print " " to. fout
line_length += code.lenght + 4
end
if line_length >= MAXLINELENGTH
Print new line character to fout.print "\n"
Reset line_length to 0
end
end
fout.close
fin.close
Basically the goal is to print letters and numbers to a documnet labeled idex.txt but the user input characters would be translated in morse code in the txt document

So your taking input and converting to Morse code then logging it to a text document? Never tried that language but it looks similar to visual basic.
If so, I don't see a loop set up to parse through the input string. You will need to iterate through each character, then I'm assuming there is a separate class (or function?) that will return the Morse code for each character.
Sorry I've only ever used c++ and java

Yea Im really bad at this, I was super excited to learn it but its not going well. I cant think in a rules and order kinda thing, I'm just more free thinking I need to be able to change stuff to however I want. So I just don't understand what I am looking at lol.

Well I'm self taught I guess it's just a personality thing lol. Basically think of coding like this : write this program : make a pb+j sandwich, literally write down EVERY step you need to do in order to make it... Kinda weird analogy, but depending on how deep you go that could end up being tens of thousands of lines of code.
So in your case write down on paper EVERY step you need to do to get morse code from the input and write it to a text file. That will be your pseudocode now you need to translate that into code. Remember Google is your friend when you need to find the syntax needed to do what you want.
Wish I had more free time and experience in ruby to help

Easiest thing to do, will be to loop through the entire input string and parse each letter at a time. Had to do a morse-code conversion program in several older languages (Pascal, Fortran, Ada, C, C++) for my Programming Languages course last semester. Pseudocode was something like:
Get input from user (or parse an input file).
Store input into a string (or a string array if multiple lines).
Loop through string and check each letter individually and look up what the morse-code equivalent is.
Store the morse code equivalent in a new string inside the loop.
When you hit the end of the string (end of the loop), save the morse string to a file.
In the loop, checking each individual letter, a case statement (or if else-if else's) will be the easiest (more typing, but easier logic).
So, for example, here's a C++ version that I wrote for my class last semester:
Code:
#include <cstdlib>
#include <iostream>
#include <string>
#include <cctype>
using namespace std;
string search(char character);
int main()
{
string encryptionString = "";
string morseString = "";
cout << "Enter a sentence, containing only letters and blanks \nand ending with a period, to convert to morse code: " << endl;
getline(cin, encryptionString);
//remove ending period, if it exists
if(encryptionString[encryptionString.length() - 1] == '.')
{
encryptionString.erase(encryptionString.length() - 1);
}//if
for(int i = 0; i < encryptionString.length(); i++)
{
encryptionString[i] = toupper(encryptionString[i]);
}//for
int index = 0;
while(index < encryptionString.length())
{
if(encryptionString[index] != ' ' || encryptionString[index] != '\n')
{
cout << " ";
morseString = search(encryptionString[index]);
cout << morseString;
}
else
{
cout << endl;
morseString = "";
}
index++;
}//while
cin.ignore();
cout << "\n\nPress enter to exit...";
cin.get();
return 0;
}//main
string search(char character)
{
string returnString = "";
if(character >= 65 || character <= 90 )
{
switch(character)
{
case 'A':
returnString = ".-";
break;
case 'B':
returnString = "-...";
break;
case 'C':
returnString = "-.-.";
break;
case 'D':
returnString = "-..";
break;
case 'E':
returnString = ".";
break;
case 'F':
returnString = "..-.";
break;
case 'G':
returnString = "--.";
break;
case 'H':
returnString = "....";
break;
case 'I':
returnString = "..";
break;
case 'J':
returnString = ".---";
break;
case 'K':
returnString = "-.-";
break;
case 'L':
returnString = ".-..";
break;
case 'M':
returnString = "--";
break;
case 'N':
returnString = "-.";
break;
case 'O':
returnString = "---";
break;
case 'P':
returnString = ".--.";
break;
case 'Q':
returnString = "--.-";
break;
case 'R':
returnString = ".-.";
break;
case 'S':
returnString = "...";
break;
case 'T':
returnString = "-";
break;
case 'U':
returnString = "..-";
break;
case 'V':
returnString = "...-";
break;
case 'W':
returnString = ".--";
break;
case 'X':
returnString = "-..-";
break;
case 'Y':
returnString = "-.--";
break;
case 'Z':
returnString = "--..";
break;
}//switch
}//if
return returnString;
}//search
For you, you would instead print to a file instead of print to screen. You'll need to look up the exact syntax for Ruby, but should be easy.
