C Sudoku solver Setting values to multi dimensional arrays I

C++ Sudoku solver. Setting values to multi dimensional arrays.

In my .h file I have a function called mySudoku(int anArray[][Size]); I have an alternate constructor in Sudoku.cpp called mySudoku::mySudoku(int anArray[][Size]) (*Size = 9) and I have to set the values of a different array called Data[9][9] to the values passed into the constructor. I have tried many different ways and everytime I get the error: incompatable types int to int[9][9]. or I get the error: undefined reference to \'vtable for mySudoku\' I can\'t seem to figure out how to set int (*)[9] equal to a array [9][9]. Any help would be appreciated.

Solution

mySudoku.h:

#ifndef MYSUDOKU_H_
#define MYSUDOKU_H_

class mySudoku{
private:
   int data[9][9];
   static const int Size = 9;
public:
   mySudoku(int anArray[][Size]);
   void print();
};

#endif

mySudoku.cpp:

#include \"mySudoku.h\"

#include <iostream>
using namespace std;

mySudoku::mySudoku(int anArray[][Size]){
   // data is a static reference to the array, so we can\'t set an array pointer directly to data
   // data = anArray is incorrect
   // correct way is to assign every element seperately
   for (int i = 0; i < Size; ++i){
       for (int j = 0; j < Size; ++j){
           data[i][j] = anArray[i][j];
       }
   }
}

void mySudoku::print(){
   for (int i = 0; i < Size; ++i){
       for (int j = 0; j < Size; ++j){
           cout << data[i][j] << \" \";
       }
       cout << endl;
   }
   cout << endl;
}
