Your training heart rate is computed as .7 * (220 – a) + .3 * r, where a is your age and r is your resting heart rate (your pulse when you first wake). Write a program that declares two variables, one to store a person's age 20 and the other to store a person's resting heart rate 69.15. Assign these variables values. Calculate and display this person's training heart rate.
