Function Templates in PERL

[sreemakam]

Hello,

Does any body know if PERl supports function templates just as C++ does. I have heard of object-oriented PERL. Hence, wanted to use the feature. Please give the snippet of code also in case u have any.

Thanks,

in C++ you would have:

int something( int arg1, int arg2 )
{
  ...processing...
}

in PERL this is done as follows:

sub something
{
  ...processing...
}

and called by putting an ampersand (&) at the front of the function name:

&something( val1, val2 );

Input parameters are passed via the @_ array variable.


SO a sample function would be:

sub ADD
{
  $val1 = $_[0];
  $val2 = $_[1];

  return $val1 + $val2;
}


$answer = &ADD( 2, 3 );
