C????

#include 
   
    int main() {    int a, b;    while(scanf("%d %d",&a,&b) != EOF) {        float c = a / (b / 100.00) / (b / 100.00);        if(c < 18.5)            printf("Underweight");        else if(c >= 18.5 && c <= 23.9)            printf("Normal");        else if(c > 23.9 && c <= 27.9)            printf("Overweight");        else            printf("Obese");    }}
   

C++????

#include 
   
    #include 
    
     using namespace std;int main() {    int a, b;    while(cin >> a >> b) {        float c = a / (b / 100.00) / (b / 100.00);        if(c < 18.5)            cout << "Underweight";        else if(c >= 18.5 && c <= 23.9)            cout << "Normal";        else if(c > 23.9 && c <= 27.9)            cout << "Overweight";        else            cout << "Obese";        cout << endl;    }}
    
   

Java????

import java.io.*;public class Main {    public static void main(String[] args) throws IOException {        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));        String s;        while((s = br.readLine()) != null) {            String[] sa = s.split(" ");            int a = Integer.parseInt(sa[0]);            int b = Integer.parseInt(sa[1]);            double c = a / (b * 0.01) / (b * 0.01);            if(c < 18.5)                System.out.println("Underweight");            else if(c <= 23.9 && c >= 18.5)                System.out.println("Normal");            else if(c <= 27.9 && c > 23.9)                System.out.println("Overweight");            else                System.out.println("Obese");        }    }}

?????????????????????????????????????????C???C++???????????Java?????????????????????????????a?b?????????????????????c = a / (b / 100.00) / (b / 100.00)??c = a * 10000 / (b^2)???c??????????????
