Write a complete C++ program that: 1. Ask the user what is the amount they have in budget for the month 2. Using a cycle, ask the user what his expenses have been in the month 3. Keep a total of expenses 4. When the user finishes entering their expenses, display the amount they have left or the budget was exceeded. NOTE: Display only the amount, without any additional messages. That is, if you had $ 50.75 left over, DO NOT display "You have $ 50.75 left over this month", but only display the number 50.75
