Generating an Array of Letters in the Alphabet

Generating an array of letters in the alphabet

I don't think there is a built in way, but I think the easiest would be

  char[] alpha = "ABCDEFGHIJKLMNOPQRSTUVWXYZ".ToCharArray();

Better way to generate array of all letters in the alphabet

I think that this ends up a little cleaner, you don't have to deal with the subtraction and indexing:

char[] alphabet = "abcdefghijklmnopqrstuvwxyz".toCharArray();

How to get an easier way of generating the alphabet in C++?

Because all characters can be represented in ASCII codes ('a' starts at 97, all ASCII codes are int), you can simply make a loop to do that. For example:

char albet[26];

for (int ch = 'a'; ch <= 'z'; ch++) {
    //do ch-'a' because we start at index 0
    albet[ch-'a'] = ch;
}

and you are done!

Generate array of all letters and digits

[*('a'..'z'), *('0'..'9')] # doesn't work in Ruby 1.8

or

('a'..'z').to_a + ('0'..'9').to_a

or

(0...36).map{ |i| i.to_s 36 }

(the Integer#to_s method converts a number to a string representing it in a desired numeral system)

How to generate an array of the alphabet?

You can easily make a function to do this for you if you'll need it a lot

function genCharArray(charA, charZ) {
    var a = [], i = charA.charCodeAt(0), j = charZ.charCodeAt(0);
    for (; i <= j; ++i) {
        a.push(String.fromCharCode(i));
    }
    return a;
}
console.log(genCharArray('a', 'z')); // ["a", ..., "z"]

Generate an array of letters of alphabet in non-english and add different value for each letter in C# or VB.net

Now this is just a guess, because I'm not sure what you're aiming for but did you consider using a Dictionary object?

A Dictionary works like a dictionary in the real world. You have the unique keys and to each such key you have a corresponding value. In your case, the letters (or combos of letters) would be the keys and the numbers the actual values.

(Of course, since ut seems to be a 1-to-1 relation, the numbers can be used as keys as well.)

Please elaborate on your goal.

Most efficient method to create all the letters in the alphabet into a string

For 'most efficient' you would try to avoid List<> and LINQ.

  var sb = new StringBuilder("All", 26+3 +spare);
  for (char c = 'A'; c <= 'Z'; c++)  sb.Append(c);

  string result = sb.ToString();

but to be honest you would have to benchmark the various answers here.

How to create an alphabet with RexExp object?

I don't think you can do that with a regex object. Regexes are for matching against values you already have, rather than creating new ones. You can create the alphabet by looping over character code ranges, if that helps?

var letters = [];// loop over character codes of the lowercase alphabetfor (var i = 97; i < 123; i++) {  // push each letter in to the array  letters.push(String.fromCharCode(i));}// create an elementvar elem = document.createElement('p');// set the innerHTML to the joined arrayelem.innerHTML = letters.join(',');// put the element on the pagedocument.body.appendChild(elem);
