print @a;

Whenever you need to embed single-quotes in a single-quoted string, you need to first close the single-quoted string, add a backslash-escaped single-quote, then reopen the single quoted string immediately afterwards (all of this is to appease the shell's parser, it has nothing to do with perl).

So
Code:
'

becomes
Code:
'\''

for every instance of a single quote you'd like to place inside a single-quoted string.

Sorry Alister but the problem as in radoulov solution
