Write a program that will perform Factorial and Fibonacci calculations recursively. Allow the user to select what function they want to calculate and the value they want to calculate. Perform user input checking and reject any input that is not valid (for example negative values) and any input whose value will overflow a 32-bit unsigned integer format. Do all the calculations in 32-bit unsigned integers. Students will have to research what input value will produce an overflow condition and reject any values at or above that limit. It is easier to code up the rejecting of the input than write the code to detect the overflow. Also, there is no time wasted doing a calculation that cannot be performed.
