Array Code Challenge

[ScriptBasic]

The BaCon project has a string append benchmark / research effort going to resolve BaCon's string management problems.

I would like to move on to array variables and how languages deal with them.

Challenge Definition:

The goal is to create an array that contains the the DEC, HEX, Symbol values for the ASCII table. (DEC 0 - 255)

Example:

Code: [Select]

ASCII[64,0] = 64
ASCII[64,1] = "40"
ASCII[64,2] = "@"

Interpreters, compilers and translators welcome.

REM SmallBASIC
REM created: 07/02/2016
dim ar(255,2)
for i=0 to 255
  ar(i,0)=i:ar(i,1)=hex(i):ar(i,2)=chr$(i)
next
? ar(64,0),ar(64,1),ar(64,2)
pause

Can you show some output from your example? (0 - 127 would be nice)

Looks great. Thanks.

What's the challenge?

I don't know of many languages that allow mix types for array elements. I know even less that don't require the array to be DIM'ed prior to use.

I wonder how many other languages can do the same?

Code: [Select]

FOR i = 0 TO 255
  ascii[i,0] = i
  ascii[i,1] = HEX(i)
  ascii[i,2] = CHR(i)
NEXT
FOR o = 0 TO 126
  PRINT ascii[o,0],"\t",ascii[o,1],"\t",ascii[o,2],"\n"
NEXT

I tried doing this in BaCon but ran into the single dimension issues before I could determine if mixed types were supported. (unlikely) BaCon has limited array support and what does work seems like a hack. BaCon only allows passing single dimension arrays as arguments to functions as well. I don't think BaCon allows returning arrays of any type. I should have saved the name C BASIC for Peter. (Crippled BASIC)

Maybe Tomaaz would have better luck as he is a BaCon fan.

[Tomaaz]

I don't know of many languages that allow mix types for array elements.

Python, Ruby, Lua, Tcl, Java, C#, JavaScript, Perl...

I know even less that don't require the array to be DIM'ed prior to use.

Python, Ruby, Lua, Tcl, Java, C#, JavaScript, Perl...

The whole challenge is completely pointless. What about something like this:

Write a program that writes on the screen values of sinus for numbers form 1 to 100 without using any variable name.

Perl

Code: [Select]

print for (map {sin() (1..100)})

How many other languages can do it?

Or:

What language let you do arithmetic operations on whole arrays?

Ruby

Code: [Select]

cities  = %w[ London Oslo Paris Amsterdam Berlin ]
visited = %w[Berlin Oslo]
puts "I still need to visit the following cities:", cities - visited

How many other languages can do it?

You can find something specific for almost every language (either good or bad), but what does it proof?

[ScriptBasic]

The whole challenge is completely pointless.

Can you post a Python example for grins?

[Tomaaz]

Can you post a Python example for grins?

Code: [Select]

a = []
for x in range(0, 256):
a.append([x, hex(x), chr(x)])
for x in range(0, 256):
print(a[x][0], a[x][1], a[x][2])

Happy?

Yes. Thanks for your time and efforts on this topic.

Here is a Perl code. Just copy it to your terminal (you need to have Perl installed, of course) and hit enter:

Code: [Select]

perl -e 'for (0..255) {$a[$_] = [$_, sprintf("%x", $_), chr($_)]; print $a[$_][0], " ", $a[$_][1], " ", $a[$_ ][2], "\n"};'

Or you can run this from the file:

Code: [Select]

for (0..255) {$a[$_] = [$_, sprintf("%x", $_), chr($_)]};
for (0..255) {print $a[$_][0], " ", $a[$_][1], " ", $a[$_ ][2], "\n"};

Or something more readable:

Code: [Select]

for $x (0..255) {
$a[$x] = [$x, sprintf("%x", $x), chr($x)];
}
for $x (0..255) {
print $a[$x][0], " ", $a[$x][1], " ", $a[$x][2], "\n";
}

Here is a Perl code. Just copy it to your terminal (you need to have Perl installed, of course) and hit enter:

Or I could just use my Perl extension module and run it from Script BASIC. 

Code: [Select]

DECLARE SUB pl_Init ALIAS "pl_Init" LIB "sbperl"
DECLARE SUB pl_Eval ALIAS "pl_Eval" LIB "sbperl"
DECLARE SUB pl_Destroy ALIAS "pl_Destroy" LIB "sbperl"

pl_Init
pl_code = """
for (0..255) {$a[$_] = [$_, sprintf("%x", $_), chr($_)]};
for (0..255) {print $a[$_][0], " ", $a[$_][1], " ", $a[$_ ][2], "\n"};
"""

pl_Destroy

Wow!  Myself, I would just use Perl, but if someone feels more familiar with BASIC (but wants to have Perl power) it may be a good solution.

Here is a Script BASIC Perl SQLite example. Perl has an extensive library of goodies that are only a use away. This is a simple interface that allows me to load Perl scripts dynamically, run them and get variable values.

                      or die $DBI::errstr;

I also have language extension modules for TinyScheme and MyBASIC. The BBC extension module only addresses the graphic syntax of the BASIC.
