NAME ^

Perl::Critic::Policy::ControlStructures::ProhibitCStyleForLoops - Write for(0..20) instead of for($i=0; $i<=20; $i++).

AFFILIATION ^

This Policy is part of the core Perl::Critic distribution.

DESCRIPTION ^

The 3-part for loop that Perl inherits from C is butt-ugly, and only really necessary if you need irregular counting. The very Perlish .. operator is much more elegant and readable.

    for($i=0; $i<=$max; $i++){      #ick!
        do_something($i);
    }

    for(0..$max){                   #very nice
        do_something($_);
    }

CONFIGURATION ^

This Policy is not configurable except for the standard options.
