Write a c++ program to compute a county property tax. The program inputs a 14-character property ID and the lot length (in feet) and the lot width (in feet) and the owners age and gross income. The county property tax is $0.02 per square foot. The program computes area * city tax rate. If owner is 70 or over and gross income is less than $10,000, compute a 25% discount on property ta, else do not.
