#include <stdio.h>

void main()

{double c,h,w,p;

char s;

printf("\n (Man please input 1,woman please input 2)\nPlease input your height,weight,sex: \n");

scanf("%lf %lf %c",&h,&w,&s);

if(s==1)

c=h-105;

else if (s==2)

c=h-107.5;

p=(w-c)/c;

if(p>=(0.1*c) && p<=(0.2*c))

printf("超重\n");

else if(p>(0.2*c) && p<=(0.3*c))

printf("轻度肥胖\n");

else if(p>(0.3*c) && p<=(0.5*c))

printf("中度肥胖\n");

else if(p<(0.2*c))

printf("偏瘦\n");

else if(p>(0.5*c))

printf("重度肥胖\n");

else

printf("正常\n");

}

我已经按您说的改了 但是运行了还是只能输出重度肥胖，这是什么回事呢，请您指点！
