Class method in Perl doesn't work, others does
I have a problem with a simple code in Perl
#!/usr/bin/perl
use strict;
use warnings;
use CGI;
my $q = new CGI;
print $q->header('text/html');
class Foo {
#print "Hello, world
";
}
my $foo = new Foo();
print $foo->header('text/html');
The first one doesn't work and says undef, the second works.
The last one doesn't work, it says that
Class method Foo::header not defined
I can't figure out why.
A:
You need to start your class with an object:
class Foo {

}
Or you could just use a prototype:
sub header {... }
A:
Change the class statement to
class Foo {
...
}
Note that your example also doesn't show the "new" keyword, which you should include to create the new object.
