c++ - How to make a program declare variable number of indefinite size arrays -


this might sound crazy wondering if possible make program declare n number of arrays of type array[] in loop using c/c++. example, sample pseudo-code:

input int _n_    run loop _n_ times such that:   declare _array1[]_   declare _array2[]_   .   .   declare _array'n'[]_

so problem here two-fold:
- declare variable length arrays
- declare variable number (i.e. n number of) such arrays.

the truth table:

task        / language         | c                   | c++ -------------------------------+-----------------------+------------------------ declare variable length arrays | use vlas            | not possible without                                |      int arr[n];    | non-standard extensions                                |                     | use std::vector<t> -------------------------------+---------------------+-------------------------- declare variable number      |  not possible   | not possible use (i.e. n number of) such arrays |  use int arr[n][k]; | vector<vector<t>>
