if (longone) *(long UNALIGNED *)pointer = (unsigned long)number; ba

#include<stdio.h>
int main()
{
int a,b,c,max;
printf("please input a,b,c;\n");
scanf("%d,%d,%d,&a,&b,&c\n");
max=a;
if(max<b);
max=b;
if(max<c);
max=c;
printf("The largest number is%d\n",max);

return 0;
}
输出数字后就报错.........
if (longone)
*(long UNALIGNED *)pointer = (unsigned long)number;
else
*(short UNALIGNED *)pointer = (unsigned short)number;

报错是scanf函数的参数写错了
scanf("%d,%d,%d,&a,&b,&c\n");修改为scanf("%d,%d,%d\n",&a,&b,&c);

看代码是求3个输入整数的最大值
两个if后面多了分号，导致判断逻辑没有起作用，现在永远都是max=c。
