How to write a a program to read a person's age and resting heart rate and display the training heart rate

Answer 1

/***********************************************************************************

Given: age, resting heart rate

Max heart rate = 220 - age

Reserve = Max heart rate - resting heart rate

min target Heart Rate = 50% * reserve + resting heart rate

max target Heart RAte = 75% * reserve + resting heart rate

EX. 50, 80

Max heart rate = 220-50=170

Reserve = 170 - 80 = 90

min target heart rate = 50% of 90 + 80 = 45 + 80 = 125

max target heart rate = 75% of 90 + 80 = 45+22.5 + 80 = 125 + 22.5 = 147.5

-------------------------------------------------------------------------------

Ex. 40 , 80

Max heart rate = 220-40 = 180

Reserve = 180 - 80 = 100

min target heart rate = 50% * 100 + 80 = 50+80 = 130

max target heart rate = 75% * 100 + 80 = 75+80 = 155

#include <stdio.h>

min_target_heart_rate = 0.5 * reserve_amt + resting_heart_rate;

max_target_heart_rate = 0.75 * reserve_amt + resting_heart_rate;
