Write a C++ program to compute effective interest rate. Formula is e=(1+r/n)^n - 1. Where n is the total number of compoundings and r is the annual interest rate. Your job will be to write a program that gets the compoundings per year, number of years, and the annual interest rate from the keyboard and then calls a function that takes in those three inputs as parameters to compute and return the effective interest rate. The function shouldnt return 0 if any of the three parameters are negative numbers. Thanks in advance and will like!
