Hello,

Can someone please help that how value of p is coming out as 1 through 17.

My understanding is p should be equal to $. (line number) and it should be printed from 3 to 19 rather 1 to 17.

Thanks in advance!

#!/usr/bin/perl 
##use warnings; 
while(<>){
if($p=3..1) 
{
print "p is $p\n"; 

} 
}

When i run the same code on a file that has fifteen lines, it returns following

p is 1

p is 2

p is 3

p is 4

p is 5

p is 6

p is 7

p is 8

p is 9

p is 10

p is 11

p is 12

p is 13

p is 14

p is 15

p is 16

p is 17

Also what is difference when i have $p=3..1 vs ($p=3)..1 in if statement above
