Write a C$++$ that calculates: A county collects property taxes on the assessment value of property, which is $60$ percent of the property$$s actual value. If an acre of land is valued at $$10,000,$ its assessment value is $$6,000.$ The property tax is then $75$ for each $$100$ of the assessment value. The tax for the acre assessed at $$6,000$ will be $$45.$ Write a program that asks for the actual value of a piece of property and displays the assessment value and property tax. Include the use of three boolean flags to ensure positive user input.
