What is join() Function in Perl programming?
|
|
Explanation |
|
The join() function joins a list into a string using a separator.
Syntax:
join SEP,LIST;
In the above syntax, join() function takes a "seperator", a "list" as arguments.
Example:
#! C:\programfiles\perl\bin\perl
print "content-type: text/html\n\n";
@color = ('Green','Orange','Blue','Pink','Peach','Black');
$col1 = join("+", @color);
print("The strings joined using '+': $col1,\n");
print "<br>";
$col2 = join("-", @color);
print("The strings joined using '-': $col2,\n");
Result:
The strings joined using '+': Green+Orange+Blue+Pink+Peach+Black,
The strings joined using '-': Green-Orange-Blue-Pink-Peach-Black,
In the above example first the elements are joined using a "+", then using a "-".
