![Task](http://static.miraheze.org/rosettacodewiki/thumb/b/ba/Rcode-button-task-crushed.png/64px-Rcode-button-task-crushed.png)
You are encouraged to solve this task according to the task description, using any language you may know.
Take the string "alphaBETA", and demonstrate how to convert it to UPPER-CASE and lower-case.
4D
$string:="alphaBETA" $uppercase:=Uppercase($string) $lowercase:=Lowercase($string)
ActionScript
var string:String = 'alphaBETA'; var upper:String = string.toUpperCase(); var lower:String = string.toLowerCase();
Ada
with Ada.Characters.Handling; use Ada.Characters.Handling; with Ada.Text_Io; use Ada.Text_Io; procedure Upper_Case_String is S : String := "alphaBETA"; begin Put_Line(To_Upper(S)); Put_Line(To_Lower(S)); end Upper_Case_String;
C
Standard: C
Compiler: GCC gcc (GCC) 3.4.4 (cygming special, gdc 0.12, using dmd 0.125)
Library: libc
// Demonstrate toupper and tolower for // standard C strings. // This does not work for multibyte character sets. #include <ctype.h> #include <stdio.h> //optional - un-comment to use function versions of //toupper and tolower, leave commented //to use macro versions //#undef toupper //#undef tolower
//upper-cases s in place and returns it char *str_toupper(char *s) { char *originalstring; originalstring=s; while(*s) { *s=toupper(*s); s++; } return originalstring; } //lower-cases s in place and returns it char *str_tolower(char *s) { char *originalstring; originalstring=s; while(*s) { *s=tolower(*s); s++; } return originalstring; } int main(int argc, char *argv[]) { char *s=NULL; char t[255]="abcdefg 123 ABCDEFG"; //edit in place str_toupper(t); printf("uppercase: %s\n", t); str_tolower(t); printf("lowercase: %s\n", t); //use returned strings, be aware the string is still //edited in place printf("uppercase: %s\n", str_toupper(t)); printf("uppercase: %s\n", str_tolower(t)); return 0; } Output: uppercase: ABCDEFG 123 ABCDEFG lowercase: abcdefg 123 abcdefg uppercase: ABCDEFG 123 ABCDEFG uppercase: abcdefg 123 abcdefg
C++
Standard: ANSI C++
Compiler: GCC g++ (GCC) 3.4.4 (cygming special)
Library: STL
This method does the transform in-place. Alternate methods might return a new copy or use a stream manipulator.
/// \brief in-place convert string to upper case /// \return ref to transformed string void str_toupper(std::string &str) { std::transform(str.begin(), str.end(), str.begin(), std::toupper); }
/// \brief in-place convert string to lower case /// \return ref to transformed string void str_tolower(std::string &str) { std::transform(str.begin(), str.end(), str.begin(), std::tolower); }
here is sample usage code:
#include <iostream> using namespace std; int main() { string foo("_upperCas3Me!!"); str_toupper(foo); cout << foo << endl; str_tolower(foo); cout << foo << endl; return 0; }
C#
string array = "alphaBETA"; System.Console.WriteLine(array.ToUpper()); System.Console.WriteLine(array.ToLower());
ColdFusion
converting a string literal
<cfset upper = UCase("alphaBETA")> <cfset lower = LCase("alphaBETA")>
converting the value of a variable
<cfset string = "alphaBETA"> <cfset upper = UCase(string)> <cfset lower = LCase(string)>
Delphi
Compiler: ALL
writeln(uppercase('alphaBETA')); writeln(lowercase('alphaBETA'));
E
["alphaBETA".toUpperCase(), "alphaBETA".toLowerCase()]
Forth
create s ," alphaBETA" s count type s count 2dup upper type s count 2dup lower type
Output:
alphaBETA ALPHABETA alphabeta
JavaScript
alert( "alphaBETA".toUpperCase() ); alert( "alphaBETA".toLowerCase() );
Output:
ALPHABETA alphabeta
Perl
Interpreter: Perl v5.x
my $string = "alphaBETA"; my $uppercase = uc($string); my $lowercase = lc($string);
Python
s = "alphaBETA" print s.upper() print s.lower()
Ruby
Interpreter: Ruby 1.8
"alphaBETA".downcase "alphaBETA".upcase "alphaBETA".swapcase
Seed7
writeln(upper("alphaBETA")); writeln(lower("alphaBETA"));
SQL
--tested in Microsoft SQL 2005 declare @s varchar(10) set @s = 'alphaBETA' print upper(@s) print lower(@s)
Tcl
set string alphaBETA string toupper $string # ==> ALPHABETA string tolower $string #==> alphabeta
