}
大家帮我看看看，为什么结果总是错误？

#include<stdio.h>
int smin(int *x)
{
int sum=0,*p;
int minsum;
p=x;
minsum=*p+*(p+1)+*(p+2);
for(p=x+1;p<(x+10);p++)
{
sum=*p+*(p+1)+*(p+2);
if(minsum>sum) minsum=sum;
}
return(minsum);
}
void main()
{
int a[10],i,min=0;
int *p;
p=a;               
printf("please input 10 numbers:");
for(i=0;i<10;i++)
scanf("%d",p++);
p=a;
min=smin(p);
printf("the min sum of three numbers is %d\n",min);
}
