Question

C++

Your solution will consist of the following four files: HeartRates.h (class specification file) HeartRates.cpp (class implementation file) 200_assign4.cpp (application program) 200_assign4.pdf (sample runs)

Answer 1

/*C++ program that prompts user to enter the first and last names
then day, month and year values and then display the name ,date of birth
and then prompt current date and then find age and the find
maximum heart rate and target heart rate range*/
