How to print int and char together from 2d array

Question

What I want to get is 4x4 matrix or larger and replace integers of center to characters. such as

 1   2   3   4
 5   6   7   8
 9  10  11  12
13  14  15  16

fill out numbers not by manual writing. It can be 8X8 10X10 matrix

 1   2   3   4 
 5   A   B   8
 9   B   B  12
13  14  15  16

void (int arr[MAX_ARRAY_SIZE][MAX_ARRAY_SIZE],int nrow){

    for (int row = 0; row < nrow; row++)
    {
        for (int col = 0; col < nrow; col++)
        {
            arr[row][col] = i++;
            if (nrow / 2 == row && nrow / 2 == col)
            {
                arr[row - 1][col - 1] = 'A';
                arr[row - 1][col] = 'B';
                arr[row][col - 1] = 'B';
                arr[row][col] = 'A';
            }
        }
    }
    
    for (int row = 0; row < nrow; row++)
    {
        for (int col = 0; col < nrow; col++)
        {
            cout<< arr[row][col];
        }
        cout << endl;
    }
}

I tried to make it char by

char charArray[MAX_ARRAY_SIZE][MAX_ARRAY_SIZE]=arr[MAX_ARRAY_SIZE][MAX_ARRAY_SIZE];

But It shows weird characters and if I do

charArray[row][col] =i +'0';

It shows me numbers before 10 and over 10 would be the same weird charaters.

Can anybody help me please?

Run this code and let me know if you have any qeustions.

#include <iostream>

const int MAX_ARRAY_SIZE = 8; // You can change this to create larger matrices

void fillMatrix(char arr[MAX_ARRAY_SIZE][MAX_ARRAY_SIZE], int nrow) {
    char ch = 'A';
    int center = nrow / 2;

    for (int row = 0; row < nrow; row++) {
        for (int col = 0; col < nrow; col++) {
            if (row == center && col == center) {
                arr[row][col] = ch++;
            } else {
                arr[row][col] = ch;
            }
            ch++; // Move to the next character
        }
    }
}

int main() {
    char charArray[MAX_ARRAY_SIZE][MAX_ARRAY_SIZE];

    fillMatrix(charArray, MAX_ARRAY_SIZE);

    for (int row = 0; row < MAX_ARRAY_SIZE; row++) {
        for (int col = 0; col < MAX_ARRAY_SIZE; col++) {
            std::cout << charArray[row][col] << "\t";
        }
        std::cout << std::endl;
    }

    return 0;
}
