萌新学习编程，根据参考书写程序，到这一步迟迟不出结果。已经不是第一次了。用getchar（）也不行，有大佬能解决吗？
这是代码：
#define ADJUST 7.31
int main (void)
{
const double SCALE = 0.333;
double shoe,foot;
printf("Shoe size (men's) foot length\n");
shoe = 3.0;
while (shoe < 18.5);
{
foot = SCALE * shoe + ADJUST;
printf("%10.1f %15.2f inches\n",shoe,foot);
shoe = shoe + 1.0;
}
printf("If the shoe fits,wear it.\n");
return 0;
}
