Can you help me with my C++ coding? (by editing my code):

I want you to create 4x7 (4 columns, 7 rows) board on C++ that all values are zero.

For example:

Then, 2 different players should be able to change the zero values as 1 or 2 (both players can use 1 and 2) and if one player tries to change already changed value or enters different value then 1 or 2, the program should warn the player.

For example:

*** The matrix board should be displayed with its final form after each player makes their move.

Here is the code I made so far, you can use it. Can you convert it into C++ language (also I believe there is a problem about entering row and columns number):

#include  using namespace std; // function to print the board void printarray(int arr[][4]){ for (int i = 0; i > r1 >> c1; if (arr[r1][c1] != 0){ cout > val1; if (val1 != 1 && val1 != 2){ cout > r2 >> c2; if (arr[r2][c2] != 0){ cout > val2; if (val2 != 1 && val2 != 2){ cout > c; if (c == 'n'){ break; } } // Print the output cout   ||0|0|0 1 0 0 0 1 |0 0 | 0 0 0 1 |0 0 1 10 0 0 0 TOTO 0 | 0 0 01 101 0 1 1 0 0 101 001 IOIOIOIO ***************** 0 1 2 3 ekil 1.a.
