Most people just say “Happy Birthday” to each other over social networks like Facebook and Twitter with the same 14 predictable letters.   Why not say it with code?   If you’re a developer you already understand.      Before you ask … Yes, I really did write and run the QBasic 4.5 version in 16-bit mode running www.DosBox.com on Windows 7 x64.   Oh, and no it’s not my birthday.

With PowerShell

1..4 | % {if ($_ -ne 3) {Write-Host "Happy Birthday to You!"} else {"Happy Birthday Dear Jeff"}}

With C# Console Application

for (int i = 0; i <= 3; i++) { Console.WriteLine(((i == 2) ? "Happy Birthday dear Jeff" : "Happy Birthday to You!")); }

With JavaScript

With Command Prompt

@ECHO OFF
FOR %%A IN (1 1 2 1)
DO (
IF %%A == 1 ECHO "Happy Birthday to You!"
IF %%A == 2 ECHO "Happy Birthday dear Jeff"
) 
:EOF

With QBasic 4.5  (oh yes I did!)

CLS
FOR x = 1 TO 4
        IF x = 3 THEN
                PRINT "Happy Birthday dear Jeff!"
        ELSE
                PRINT "Happy Birthday to You!"
        END IF
NEXT x
FOR x = 37 TO 1000
        SOUND x, 1
NEXT x
