Tutoring programming, conversions between strings and arrays are relevant. The tutor shows an easy way to do it in Perl.<\/h1>\n

 
\nConverting a string to a character array is a common task in small programs, especially ones that accept user input. While some languages have a built-in function, often named toString() or something similar, Perl has none I know of.<\/p>\n

The conversion is easy to do in Perl nonetheless, using Perl’s built-in split<\/strong>(\/separator\/, $inputstring<\/em>) function, which takes the $inputstring and breaks it apart at the separators, or just character by character if no separator is given. The resulting characters can be fed, one by one, into an array:<\/p>\n

#!\/usr\/bin\/perl
\nprint “Please enter a string.”;
\n$userstring=<STDIN>;
\n@arra=split(\/\/,$userstring);
\n$i=0;
\nwhile($arra[$i]){
\nprint “Character $i in your new array is “.$arra[$i].”\\n”;
\n$i++;
\n}<\/p>\n

There are a couple of “finer points” in these lines of code. I’ll be talking about them in future posts:)<\/p>\n
