How to initialize 2D array of string in c++

Question

I am trying to initialized 2D array of string in c++.

std::string A = new std::string [m+1][n+1]

But this is giving me error as array size in new-expression must be constant.

In c++ you should use `std::vector` or `std::array` instead of those `new any_type[m][n]` — t.niese, Jun 29 '18 at 08:56

You could do it the C-Style String way...

char ** array = new char*[10];
for (int i = 0; i < 10; ++i) 
{
     array[i] = new char[100];
}

Then you just delete it in the opposite order you created it when done.

Using the STL is probably a good choice if you need to be safe and modern.
