求围观，大佬们这个哪里错了， 编写代码完成后A是最大值，B是中间值，C是最小值；
# include <stdio.h>
int main(void)
{
int a,b,c;
int t;
printf("请输入三个值(中间以空号分隔): ");
scanf("%d,%d,%d",&a,&b,&c);
if(a < b);
{
t = a;
a = b;
b = t;
}
if(a<c)
{
t = a;
a = c;
c = t;
}
if(b<c)
{
t = b;
b = c;
c = t;
}
printf("%d,%d,%d\n",a,b,c);
return 0;
}
运行时总是有两个垃圾值
