First off, in most cases, it doesn’t matter. Perl is usually smart enough to figure out if something’s a string or a number from context. If you have a scalar value that contains a number, you can use it interchangeably as a string or a number based on what operators you use (this is why Perl has different operators for addition and string concatenation).
If you do want to force something to be unambiguously a string, there are many ways to convert an integer into a String in Perl. But here we will discuss how to convert 0 into a String.
Approach 1: By using double quote interpolation
Perl
#program to convert 0 to string my $x = 0; print qq("$x"); |
Output
"0"
Approach 2: By concatenation with an empty String
Perl
#program to convert 0 to String my $x = 0; my $st = q[].$x ; print qq("$st"); |
Output
"0"
