int main()

//weight in kilograms

float kilograms;

//height in meters

float meters;

//enter the values

cout<<" enter your weight in kilograms ";cin>>kilograms;

cout<<" enter your height in meters ";cin>>meters;

//calculate BMI

//formula: weight in kilo / (height in meter)*(height in meter)

float BMI = kilograms / (meters*meters);

cout<<" your BMI is "<<BMI<<endl;

if(BMI<18.5)

{

//BMI < 18.5 Underweight

cout<<" you are under weight";

}

{

//18.5 <= BMI < 25.0 Normal

cout<<" you are normal";

}

//25.0 <= BMI < 30.0 Overweight

cout<<" you are Overweight";
