In the same line as my last question.... once I tried to understand how Perl was interpreting string comparisons, I started experimenting with different strings.
What is Perl doing here? Why doesn't it use the "if" statement as a condition? It reassigns the variable value instead of using it as a conditional statement in the following code:
$password=bill; if ($password = 'howard') {
= is Perl's assignment operator. This means set $password to 'howard'. I believe your were looking for == which is a logical comparison operator, but unfortunately, that still wouldn't do the trick. == is for comparing the equality of numbers, but you want to compare two strings. For that you need Perl's string comparison operator, eq. So to fix the line above try:
if ($password eq 'howard') {
Hope that helps.

print "'$password' is a valid password.\n"; }else { print "'$password' is not valid.\n"; }
******* This results in a printout that says: 'howard' is a valid password.
Thank you again,
