Question

Write a function which asks users to enter names, heights, and weights of eachperson. For simplicity, let's assume names contain no white space - for example, justfirst names like John, Mike or Luke (so you can use cin >> name to get the name).Also assume height will range from 1.3 to 2.0 meters (which means if someoneenters a height that is less than 1.3 or greater than 2.0, show an error message andkeep asking user to enter them until they enter the correct value) and assume weightranges from 40 to 150 kg (so if user enters weight that less than 40 or greater than150 then show error message and keep asking user to enter again until they enterthe correct value) .Hint: create one array to store names, one array to store heightsand one array to store weights.3.Write a function to calculate the BMI from each weight and height collected above.The formula for BMI isBMI = weight / (height * height)Hint: Create an array BMIs that has the same size as the 3 arrays above: eachelement in the BMIs array will correspond to the BMI of each person.4.Write a function to display results: The text of result is up to you but it must have: theperson name, the BMI of that person and the result from that BMI (underweight,normal weight over weight or obese). Hint: read the first part of the question to findout how to determine underweight, normal weight, ... based on BMI.5.Inside the main function, use those functions you created above to ask the user enterinformation, calculate BMI and display the result

code:

#include <iostream>
using namespace std;
void getData();
void calculateBMI(); //functio prototypes
void display();
string names[5];
double height[5]; //declarig global varables
double input;
double weight[5];
double BMI[5];
int main()
{
getData(); //reading input data
calculateBMI(); //calculating bmi
display(); //prinitng details
return 0;
}
void getData()
{
for(int i=0;i<5;i++)
cin>>names[i];
for(int i=0;i<5;i++)
{
cin>>input;
while(input<1.3 ||input>2.0)
{
cout<<"enter corrct coorect values"<<endl;
cin>>input;
}
height[i]=input;
}
for(int i=0;i<5;i++)
{
cin>>input;
while(input<40 ||input>150)
{
cout<<"enter corrct weight values coorect values"<<endl;
cin>>input;
}
weight[i]=input;;
}
for(int i=0;i<5;i++)
{
cout<<names[i]<<" ";
cout<<height[i]<<" ";
cout<<weight[i]<<" ";
cout<<endl;
}

}
void calculateBMI()
{
for(int i=0;i<5;i++)
{
double b;
b=weight[i]/(height[i]*height[i]);
BMI[i]=b;
}
}
void display()
{
for(int i=0;i<5;i++)
{
cout<<names[i]<<":";
cout<<BMI[i];
if(BMI[i]<=18.5)
cout<<"under Weight"<<endl;
else if(BMI[i]>18.5&&BMI[i]<=24.9)
cout<<"normal weight"<<endl;
else if(BMI[i]>25&&BMI[i]<=29.9)
cout<<"over weight"<<endl;
else if(BMI[i]>=30)
cout<<"obesity"<<endl;
}
}
