Using C++ Language

Now, you will modify the above program to group the four parameters (i.e., name,
weight, feet, and inches) into a global struct called Patient. Then, instead of
declaring these four variables individually in main, you will declare a variable (or instance)
called person of the Patient struct type and read in the values from the keyboard
directly into the members of this struct variable. Again, instead of passing the individual
variables to the checkBMI function, you will pass the struct variable. And finally, when
printing out the name at the end, be sure to use the name stored in the struct variable.

Code:

#include <iostream>

#include <cmath>

#include <string>

using namespace std;

bool checkBMI(float, int, int);

int main()

{

string name; //users name

float weight; //user weight (pounds)

int feet; //feet

int inches; //inches

cout<<"Enter user name: ";

getline(cin,name);

cout<<"Enter users weight in lbs: ";

cin>>weight;

cout<<"Enter users height in ft and in.: ";

cin>>feet>>inches;

if (checkBMI(weight, feet, inches))

{

cout<<"BMI of "<<name<<" is in range."<<endl;

}

else

{

cout<<"BMI of "<<name<<" is not in range."<<endl;

}

return 0;

}

bool checkBMI(float weight, int feet, int inches)

{

int totalHeight=feet*12+inches;

float bmi=(703*weight)/pow(totalHeight,2);

return(bmi>=18.5 && bmi<=24.9);

}
