Perl: a command-line cube root program
The tutor shows an example program with a few facets to discuss.
So far as I know, to find the cube root in Perl, you need use the principle
The following program calculates the cube root of a number given with the command-line function call:
$input*=-1; #changes value to positive
$input*=-1; #restores original value
print “The cube root of $input is $out\n\n”;
I’ll be explaining some ins and outs of this program next post:)
