void printIndex(char str[]) {
    int i;
    cout << "Enter the address: ";
    cin >> i;
    while (!std::cin || i < 0 || i >= strlen(&str[0])) {
        cout << "Error! Wrong address!\nEnter the address: ";
        cin.clear();
        cin.ignore(numeric_limits<streamsize>::max(), '\n');
        cin >> i;
    }
    cout << "Place at index " << i << " is " << str[i] << "\n";
}

int main() {

    // NOTE: Do not edit this

    char location[100] = "CodeChumIsLoveAndProgrammingAsWellYey";
