Programming Challenge 11.11 - Monthly Budget
/* Monthly Budget - A student has established the following monthly budget:
* Housing: 500.00 Utilities: 150.00
* Household Expenses: 65.00 Transportation: 50.00
* Food: 250.00 Medical: 30.00
* Insurance: 100.00 Entertainment: 150.00
* Clothing: 75.00 Miscellaneous: 50.00
This program has a MonthlyBudget structure designed to hold each of these
expense categories. The program passes the structure to a function that
asks the user to enter the amounts spent in each budget category during a
month. The program then passes the structure to a function that displays a
report indicating the amount over or under in each category, as well as the
amount over or under for the entire monthly budget. */
