Arguments in different languages

[countach44]

Sounds like a project to me, hehe you could probably do it in shell scripting (not recommended). Speaking of which, I know in a shell script something like this goes
./script foo
and $1 becomes foo, how do command line args work in C, perl, and JAVA (not implying that it's same, just curious).

in C:

#include <stdio.h>
main(int argc, char *argv[]) {
for(i=0; argv[i] != NULL; i++)
      printf("argv[%d]: %s\n", i, argv[i]);
}

in perl:

#!/usr/bin/perl
foreach(@ARGV) {
print "$_\n";
}

Java I think is similar to C, but I haven't done java in quite a while...

In C++, its nearly the same as it is in C:

#include <iostream>

using namespace std;

int main(int argc, char * argv[])
{
if (argc > 1) // argv[0] = program_name (unless I am mistaken)
cout << argv[1];  // Run a loop like the one above by gorn to see all args
return 0;
}

In Java, I am guessing?! :

public static void main (String [] args)

Actually my code would work in C++ or C :-P (all C is that way, C++ however does not workin C)

Yeah, I meant just pure C++.

P.S. *Wonders if gorn remembers me*

5 second C# hack, I dunno if it works.

using System

public class HelloWorld
{
static void Main(string[] args)
{
Console.WriteLine(args);
}
}

this wouldn't work since the WriteLine method doesn't take an array of strings (it would work if you'd write Console.WriteLine(args.ToString());

this would work though:

using System;

public class HelloWorld
{
   static void Main(string[] args)
   {
     foreach string s in args
     {
         Console.WriteLine(s);
     }
   }
}

to be honest, i'm not sure if a string array works with foreach and i'm too lazy to look it up right now..

Damn...I was hoping to see a spanish guy yelling at an american or something
