the if-else is not workingThere is no if-else in the code you posted.
Use warnings and fix the problem:
use warnings; use strict; use diagnostics; my $i = 0; my @h = 0 .. 3; ( $h[$i] eq 'N/A' ) ? 0 : $h[$i]; __END__ Useless use of array element in void context at (W void) You did something without a side effect in a context that + does nothing with the return value, such as a statement that doesn't re +turn a value from a block, or the left side of a scalar comma operator. +Very often this points not to stupidity on your part, but a failure of +Perl to parse your program the way you thought it would. For example, +you'd get this if you mixed up your C precedence with Python precedence +and said $one, $two = 1, 2; when you meant to say ($one, $two) = (1, 2); Another common error is to use ordinary parentheses to construct a + list reference when you should be using square or curly brackets, for example, if you say $array = (1,2); when you should have said $array = [1,2]; The square brackets explicitly turn a list value into a scalar val +ue, while parentheses do not. So when a parenthesized list is evaluat +ed in a scalar context, the comma is treated like C's comma operator, wh +ich throws away the left argument, which is not what you want. See perlref for more on this. This warning will not be issued for numerical constants equal to 0 + or 1 since they are often used in statements like 1 while sub_with_side_effects(); String constants that would normally evaluate to 0 or 1 are warned about.
