Python, C, Java, Javascript, Powershell
I wanted to write a blog post that shows how to generate the Fibonacci sequence (0;1;1;2;3;5;8;13;21;34;55;...) in ten languages. Then I realized I would have to relearn some older language's syntax and that would mess up my current knowledge. So this is now down to five languages.
You should see output like:
First 10 Fibinacci numbers
1
2
3
5
8
13
21
34
55
Some of the scripts put the numbers on one line.
I had to encode all the less than and greater thans to keep the browser from interpreting them.

Python
I ran this in my Mac terminal with: python fibi.py
# fibinacci series generator for the first 10 numbers
# Seeds 0 and 1
x=0
y=1
print "First 10 Fibinacci numbers"
for i in range(1,10):
t = x + y
x = y
y = t
print t
C
You need to compile this with a C compiler.

#include <stdio.h>
int main ()
{
int x=0;
int y=1;
int i,t;
printf ("First 10 Fibinacci numbers\n");
for (i=0;i<10;i++)
{
t = x + y;
x = y;
y = t;
printf ("%d ",t);
}
printf("\n");
return (0);
}
Java
Probably should have it be more object oriented, but that doesn't save any lines in this case.
You do have to have the Java dev kit installed on your system.

#include <stdio.h>
int main ()
{
int x=0;
int y=1;
int i,t;
printf ("First 10 Fibonacci numbers\n");
for (i=0;i<10;i++)
{
t = x + y;
x = y;
y = t;
printf ("%d ",t);
}
printf("\n");
return (0);
}
Javascript Load this one into a browser. Getting this to even show up in the browser was a pain. Had to remove all the html and script tags. Tag: means the tag inside of angle brackets. Close tag: means use the closing tag which is the tag proceeded with a forward slash.
Tag: html
Tag: body
Tag: script
x=0
y=1
document.write("First 10 Fibonacci numbers.")
for (i=0;i<10;i++)
{
t = x + y
x = y
y = t
document.write(t," ");
}
Close tag: script
Close tag: body
Close tag: html
Powershell
$x = 0
$y = 1
$enditer = 10
for ($i=0;$i -lt $enditer;$i++)
{
$t = $x + $y
write-host $t " "
$x = $y
$y = $t
}
write-host "End of series"
