How to put what the user picks for the row and column in the board-CodePudding

So my question is how do I put what the user enters, for example, they put row : 1 and column: 2 in my board that I made. I'm working on this in the void playerChoice function.

I've thought of some solutions to this problem like board[row][column] = 'X' in like an if statement with board[row][column] = 'O' as well. Is this alright?

Hopefully you guys can help figure this problem this out with me.

const int ROWS = 3; // For the rows 
const int COLS = 3; // For the number of coluoms;
void showBoard(const char[][COLS], int); // Shows the board 
void playerChoice(char[][COLS], char); // shows the player choice 
int winner(const char[][COLS], const char, string);

int main()
{
char board[ROWS][COLS] = { { '*', '*', '*' },{ '*', '*', '*' },{'*', '*', '*'} }; 
string winner = " ";
showBoard(board, 3); // displays the board


for (int i = 0; i < 3; i  )
{
    playerChoice(board, 'X');
    showBoard(board, 3);
    
    playerChoice(board, 'O');
    showBoard(board, 3);
}

cout << "The winner is:" << winner; 
} 


void showBoard(const char arr[][COLS], int SIZE)
{
for (int row = 0; row < SIZE; row  )
{
    for (int col = 0; col < SIZE; col  )
        cout << '|' << arr[row][col]; 
    cout << '|' << endl;
}
}


 void playerChoice(char arr[][COLS], char name)
{
int row, columns;

 

cout << "What row would you like?\n"; 
cout << "Row: ";
cin >> row; 

while (row < 1 || row > 3)
{
    cout << "Error please pick a row in between 1 and 3.\n";
    cout << "Row: ";
    cin >> row;         
    cout << endl; 

}

cout << "What column would you like?\n";
cout << "Column: ";
cin >> columns;

while (columns < 1 || columns > 3)
{
    cout << "Error,please pick a row in between 1 and 3.\n";
    cout << "Column: ";
    cin >> columns; 
    cout << endl; 
}



}
int winner(const char[][COLS], const char, string)
{
 

// working on this.


return winner; 

}

Will this work for you?

unsigned int row = 0u;
unsigned int column = 0u;
char board[3][3] = {' '};

std::cout << "Enter row: ";
std::cin >> row;
std::cout << "Enter column: ";
std::cin >> column;

// Insert a character at the User's row and column
board[row][column] = 'X';

If you want to insert the User's coordinates into the board, you'll need a different type of board.

Edit 1: A different type of board
Let's call the items of the board a Cell.
In order to store the row and column, you'll need a cell that can store the row and column:

struct Cell
{
  char c;
  unsigned int row;
  unsigned int column;
};

Cell board[3][3];
//...
board[row][column].c = 'O';
board[row][column].row = row;
board[row][column].column = column;

Yes. You can try the code below:

   if (arr[row - 1][columns - 1] == '*')
    {
        arr[row - 1][columns - 1] = name;
    }
    else
    {
        cout << "Retry" << endl;
        playerChoice(arr, name);
    }
