7-21 new fat formula

The Evening News reports official Twitter, obesity latest calculated as: square weight (kg) / height (m) is. If more than 25, you are fat. So this question to ask you to write a program to automatically determine a person in the end be considered fat.

Input formats:

Input gives two positive numbers in a row, followed by a person's weight (in kg) and height (in m), separated by a space therebetween. Wherein the weight does not exceed 1000 kg, height does not exceed 3.0 m.

Output formats:

First, the person's weight and output height calculation results are substituted into the formula of obesity, retained after a decimal point. If this value is greater than 25, in the second line of the output  PANG, or outputs  Hai Xing.

Sample Input 1:

100.1 1.74

Output Sample 1:

22.5
Hai Xing

 1. Note that body weight (kg) / height squared (m) is the square of the denominator is not the square of the ratio, I started wrong.

2. Retain output formats to one decimal.

#include<iostream>
using namespace std;
int main(){
    double d1,d2,sum;
    cin>>d1>>d2;
    sum=d1/(d2*d2);
    printf("%.1f\n",sum);
    if(sum>25) cout<<"PANG";
    else cout<<"Hai Xing";
}
