Töbök tömbjeinek maximális indexeit, ill. elemeinek maximális indexeit hogyan lehet megadni Perlben?

Jaj, bocsi hogy segítek. Egyébként ez a válasz, mégis mit gondoltál, külön utasítás van rá?

OK. Now for the straight answer. Multidimensional arrays in perl are actually arrays of references to arrays. This is because arrays can only contain scalars and an array is not a scalar. To get the length of an inner dimension you can use this notation

Code:

$#{$myarray[0]}

where @myarray is a two dimensional array. It will return the number of columns in the first row. This is actually the highest index in the array that is pointed to by the first reference element in @myarray.
