Re: number of rows in double dimension array

[hdb]

A two-dimensional array in Perl usually is an array of array references, so the number of rows is just the number of elements in the "outer" array:

my @dd = ( [ 11, 12, 13], [ 21, 22, 23], [ 31, 32, 33], [41, 42, 43], 
+);
print "Number of rows: ", scalar @dd, "\n";
