The Karvonen formula is one method for calculating the training heart rate (THR). THR=[(220-AGE)-RHR]xIN TERN+RHR

where AGE is the age (years), RHR the rest heart rate, and INTERN is the fitness level (0.55 for low, 0.65 for medium, and 0.8 for high fitness level).

Write a script file that determines the THR. The program asks the user to input his/her age (number), rest heart rate (number), and fitness level (0.55 for low, 0.65 for medium, or 0.8 for high). The program then displays the training heart rate using an fprintf command (The training heart rate for a XXX old individual with a rest heart rate of XXX is XXX.). Please note that the resting heart rate range anywhere from 40 to 100 beats per minute.

Execute your program for a 25 years old male, with RHR=80 beats per minute, and a fitness level of 0.65.
