变量a运算前并没有赋值 scanf给a赋值在最后面，要把它放前面
scanf("%f",&a); printf("foot=%d inch=%d\n",t1,t2); 小数是没有余数的，不能取余 inch=a%30.48*12.0; 可以修改为以下代码  程序代码：#include <stdio.h> int main(void) { int foot, inch; int meter; scanf("%d", &meter); foot = meter / 30.48; inch = (meter - 30.48 * foot) / 30.48 * 12; printf("foot=%d inch=%d\n", foot, inch); return 0; } |
#include <stdio.h>
int main()
{
double a;
double foot;
double inch;
int t1;
int t2;
foot=a/30.48;
t1=foot;
inch=a%30.48*12.0;
t2=inch;
scanf("%f",&a);
printf("foot=%d inch=%d\n",t1,t2);
return 0;
}
