Need C language code for Body Mass Index program.

Answer 1

There are already created programs for BMI. However, if you access Google, you will notice that there are users who posted source code for various applications related to BMI. I recommend accessing Google and then visit the first link. There is a code of a BMI program. Since the author is mentioned in the code, you can use the following one to build or adjust the program's settings:

#include<iomanip>

using namespace std;

int main()

{
    float weight;
    float height;
    float bmi;
    char response;

    do 
    {
    cout << "*****************************\n";
    cout << "Please enter your weight (lbs): ";
    cin >> weight;
    cout << "Please enter your height (inches): ";
    cin >> height;
    bmi = (weight / pow(height,2)) *703;
    cout<<"\n";
    cout << fixed << showpoint << setprecision(2);
    cout<<"Your BMI is " << bmi << endl;

    if (bmi < 18.5)
       {  
       cout << "You are underweight!" << endl;
       cout << "Eat more!!" << endl;
       }
       else if (bmi >= 18.5 && bmi <25)   
       cout << "You are normal!"<<endl;
       else if (bmi >= 25 )
       cout << "You are overweight!"<<endl;
       else
       cin.get();

       cin.get();
       cout << endl;

       cout << "Would you like to enter the information again? ";
       cin >> response;
    }
   while (toupper(response) == 'Y');
   cout << "Okay, see you next time.." << endl; 
return 0;
}
