This document defines a C++ FinancialCalculator class with methods to calculate financial metrics like future value, rate of return, acid test ratio, and find minimum/maximum values in arrays. It also defines a FVc class that inherits from FinancialCalculator to calculate future value compounded over multiple periods. The main function uses the classes to build a menu-driven financial calculator application that prompts the user for input values and displays output values for different calculations.
