   3. (0 pts) I didn't read the notes carefully.
2. [20pts] Assume the following declarations and fill in the table with either the type of the given expression, or "error" if appropriate.
   

   
   double x;
   string s;
   double* A;
   int** M;
   string** W;

[10pts] Consider a variable A of type int** that is initialized so we have the situation depicted in the picture: . Write a complete definition of function print_col that could be called like this print_col(A,5,4,1) (assuming the above situation) to print the index 1 column of the array A. Thus, the call print_col(A,5,4,1) would produce the output shown below. 1 11 21 31 41 Note: the function should work for any 2D array of ints with proper dimensions and any column number.
