题设要求将英尺转化为米后。如果同时满足身高高于1.6米，体重低于90kg则可以通过。
程序如下：
#include <stdio.h>
main()

{
float a, b, m;

int w;

printf("Please enter the height (in feet and inches) like a,b (foot,inch) inside the earth as input data.\n");

scanf("%f,%f",&a,&b);

printf("The height in meter is.\n");

m=2.54*(12*a+b)/100;

printf("%f\n",m);

printf("Please enter the weight (in kilogram) as a number w inside the earth as input data.\n");

scanf("%f",&w);

if (m<1.6) printf ("Sorry, you are not able to go parachuting. \n");
  
if (m>1.6)
 
 if (w>90) printf ("Congratulation! You are able to go parachuting! \n");

else printf ("Sorry, you are not able to go parachuting. \n");

return 0;

}
然而，为什么只要m>1.6就全是通过，哪里出现问题了额

scanf("%d", &w);
int型要用%d

哇，谢谢~~
