    cin >> input;
    return input;

}

char get_item(){

        char item_Name[MAX_CHAR+1];
        cout << "Please, enter name of item you would like "
        << "to purchase"
        << endl;
        cin.getline (item_Name, MAX_CHAR ,'\n');
        cin.ignore(MAX_CHAR, '\n');
        return item_Name[MAX_CHAR];

    
}

void run_shopping_cart_program(){

    char item[MAX_CHAR+1] = {'\0'};
    item[MAX_CHAR] = get_item();



    cout << item[MAX_CHAR] << "here........" << endl;

    
}


line 72
cout << item[MAX_CHAR] << " here........" << endl;

assuming "foo Bar" for input.
desired output
foo Bar here........

actual output
┬┐here........


Thank you in advance for any help or direction!
