Sorting Arrays in Alphabetical Order, capitals and lowercase

[reymalile]

What is it you are trying to achieve?
I am trying to sort arrays in alphabetical order


What is the problem you are having?
When I am sorting capital and lowercases, i change the capitals into a lowercase, sort them but then I cant change the capitals I changed to lowercase, back to capital.


Describe what you have tried to solve this problem
I tried using two arrays however theres a problem when sorting

Turing:

var firstName : array 1 .. 40 of string var HowMany : int var first : string (1) var lowercase : string := "" var change : flexible array 1 .. 20 of string proc total     var n : flexible array 1 .. 40 of string     var x : flexible array 1 .. 40 of string     var ctr : int     ctr := 0     loop         ctr += 1         HowMany := ctr         put "Enter name (xxx to exit): "         get n (ctr)         if ord (n (ctr) (1)) >= 65 and ord (n (ctr) (1)) <= 90 then             var i : int := 0             i += 1             x (ctr) := n (ctr)             n (ctr) := Str.Lower (n (ctr) (1)) + n (ctr) (2 .. length (n (ctr)))         elsif n (ctr) = "xxx" or n (ctr) = "XXX" then             new n, (ctr - 1)             HowMany := ctr - 1             exit         end if     end loop     var temp, temp1 : string     for ctr1 : 1 .. HowMany - 1         for ctr2 : ctr1 + 1 .. HowMany             if n (ctr1) > n (ctr2) then                 temp := n (ctr1)                 n (ctr1) := n (ctr2)                 n (ctr2) := temp             end if         end for     end for     for ctr1 : 1 .. upper (n)         put n (ctr1)     end for end total total

Please specify what version of Turing you are using
4.1.1

Str.Upper does the opposite of Str.Lower, but... since both "abc" and "Abc" both look like "abc" when you lower the first character, you wouldn't know how to restore the word without additional information.

Since you are trying to implement a custom definition of a sort, perhaps the build-in

code:

"full_word" <compare> "ANOTHER_word"

is not the right way to go (since the comparison operators such as > are already defined as something else).

You don't actually need to store lower-case values of upper-case characters. Since str.lower returns a value and doesn't actually change the parameter, you can use it in a condition.

code:

if Str.Lower (string1) > Str.Lower (string2) then     swap (string1, string2) end if

thanks insectoid, your code worked
