Not sure what is needed. This will at least compile and run:

#include <iostream> 

using namespace std; 

int main()
{
    const int row=3;
    const int col=3;
    char arr[row][col];

    for (int i=0;i<row;i++)
    {
        for (int j=0;j<col;j++)
        {
            arr[i][j] = ' ';
        }
    }

    for (int i=0;i<row;i++)
    {
        arr[i][0] = '_';
        arr[i][2] = '_';
    }
    
    for (int j=0;j<col;j++)
    {
        arr[0][j] ='|';
        arr[2][j] ='|';
    }
    
    
    for (int i=0;i<row;i++)
    {
        for (int j=0;j<col;j++)
        {
            cout << arr[i][j];
        }
        cout << '\n';
    }
     
}

This is the output:

|||
_ _
|||

... but my instinct says this might be something to do with the game of "Noughts and Crosses" or "tic tac toe".
