Char dynamic array

Hello, I'm trying to adjust this program to make it run for customer size (s). i cant seem to figure out how to make the program accept the (s) value.

A 2d array is not created like that. Instead:
1
2
3
4
5
 
char **board= new char*[s];
for(int i = 0; i < s; ++i)
{
  board[i] = new char[s];
}


It is passed to function like so:

int* compare_board(const char **) const;

Thank you for the reply. when i add the for loop it is causing a "error C2059: syntax error : 'for' " I'm assuming i should have added the loop else where?

You can do this within a function only. Keep in mind that it is essential to initialize variables within the constructor.
