I have:

#include <iostream>
using namespace std;
(...)
int main()
{
    string x;
    int n;
    (...)
    cin >> x >> n;
    string good[x.size()+1];
    string tab[n], tab2[n];
    (...)
}

Dev C++ doesn't see any mistakes, but I have 5 compilation errors in these lanes:
0d51f7eb-98bd-4754-8632-86fafd7d0b29(43): error: expression must have a constant value

                                     ^

compilation aborted for 0d51f7eb-98bd-4754-8632-86fafd7d0b29 (code 2)

Could you tell me what's wrong?
