// extra2-1.cpp
// Print your name in big characters
#include <iostream>

cout << "Enter a 4-digit number: ";
cin >> number;

        cout << (number / 1000) << " ";

        number %= 10;
        cout << number << endl;
        return 0;
}

// extra2-3.cpp
// Print a 4-digit number in reverse order with spaces between digits
#include <iostream>
using namespace std;
int main() {
int number;

cout << "Enter a 4-digit number: ";
cin >> number;

        cout << (number % 10) << " ";

}

// extra2-4.cpp
// Program to compute a water and sewer bill

        double service;         //service charge,
        double total;           //total charge

        //ask user for the number of gallons consumed
        cout << "Enter number of gallons of water consumed: ";
        cin >> gallons;

        //calculate values
        gallon100 = gallons/100;
