In thermodynamics, the Carnot efficiency is the maximum possible efficiency of a heat engine operating between two reservoirs at different temperatures. The Carnot efficiency is given as

efficiency=(1-Th/Tc)

where Th and Tc are the absolute temperatures at the cold and hot reservoirs, respectively. Write a program in C that will prompt the user for the two reservoir temperatures in Kelvin, call a function to calculate the Carnot efficiency, and then call a function to print the corresponding Carnot efficiency to 3 decimal places.
