Re: Printing two variables in the same line

Formatting your code will make it a lot easier to read. E.g. :

if ($student = "") {
    print "Cannot find that student, try again\n";
}
else {
    print "$_ has a" . $student . "\n";
}

Also, you do not need to put a trailing semicolon at the end of your else block. All this does is create an empty statement that does nothing.

I have been advised by some people I trust, and have a huge ammount of respect for, To always put a semi-colon on the end of every statement, even those at the end of a block. While using a semi-colon on the last statement of a block is not necissary, it can help maintainablity. I can think of a hundered situations where I have gone back and added code into an existing block, and if the semi-colon is not there, when I'm adding to it later, I am likely to forget (until I try to run the code and it doesn't compile).

Hmm, I don't think I was being clear enough. The author had: `if { } else { };` [download] I'm not talking about having a semi-colon at the end of the last statment in a block. I'm talking about having a semi-colon AFTER the closing curly brace at the end of the block.	[reply] [d/l]

I'm not talking about having a semi-colon at the end of the last statment in a block. I'm talking about having a semi-colon AFTER the closing curly brace at the end of the block. That was clear to me! Personally I never put a semicolon after a block. But then I often forget to put one at the end of an `eval` statement. So perhaps if I had a coding style that put a redundant semiclon after all blocks then I wouldn't forget them where necessary? Smylers	[reply] [d/l]

Ahh Soo. :-) You are most correct that a semi-colon following the } is quite unnecessary. May the Force be with you	[reply]
