Mastering String Repetition in Perl
In programming, you often need to repeat strings. For example, in Python, multiplying a string by a number repeats it:
print("4" * 4)
# Output: 4444
However, if you try a similar expression in Perl like print "4" * 4;
, you get 16
instead of 4444
. This is because Perl’s *
operator is strictly for numerical multiplication. To repeat a string, Perl uses the x
operator. Let’s explore how to achieve string repetition in Perl with some fresh examples to deepen your understanding.
