Foil 28 Control Structures -- for Statement

From Tutorial on PERL Computational Science for Information Age Course CPS616 -- Sept 20 97. by Geoffrey C. Fox,Nancy McCracken,Tom Scavo
for ( beginning expression; endtest; doeachloop ) {
  • FOR statement-block;
}
The above loop is just like C and equivalent to:
beginning-expression;
while ( endtest ) {
  • FOR statement-block;
  • doeachloop;
}
For example, we can print the digits with:
for ( $i=0; $i <10; $i++ ) {
  • print "$i", "\n";
}
