A highway-patrol speed radar emits a beam of microwaves at a frequency designed as fe. The beam is reflected off an approaching car, and the radar unit picks up and analyzes the reflected beam, fr . The reflected beams frequency is shifted slightly from fe to fr because of the cars motion. The relationship between the speed of the car, v (in miles/hour) and the two microwave frequencies is: V=6.685e8(fr-fe)/(fr +fe) CS-125 (Computer Programming) Page 2 Ask the user to enter the values of inputs. Write a C++ program to calculate and print the speed of the car for fe=2e10 and the value of the received frequency fr is 2.000004e10. Take all variables of type double used in the program.
