Question

"Health Data has the power to inform, excite, and influence behavior that leads to improved health at the individual and population level." - The Beauty of Health Data Design an application that provides health information to the user. The application should include: 1) loops 2) files 3) methods (pass by value/pass by reference, overloading methods) 4) global / local variables / static variables coding language c++ an example of health data would be checking someone blood oxygen, temp, etc.the output needs to tell if the person is healthy or not

Answer 1

code in c++ which includes

• loops
• files
• methods pass by value/reference
• overloading methods
• global/local variables

code to copy

#include<bits/stdc++.h>
using namespace std;
int healthyMinBloodOxygenLevel=97;//example of global variables
int healthyMaxBloodSugarLevel=100;//example of global variables
int healthyMinBodyTemperature=36;//example of global variables
int healthyMaxBodyTemperature=38;//example of global variables
