就是野指针，不过想多用用指针，练习练习

#include <stdio.h>
main()
{
    int a[10]={1,2,3,4,5,6,7,8,9,10};
    int *max,*min;
    int i;
    for(i=0;i<9;i++)
    {
    if (a[i]<a[i+1])
         
        *max=a[i+1];
        else
        {
            a[i+1]=a[i];
        *max=a[i+1];
        }
        
    }
    puts("The max you want is:");
    printf("%d\n",*max);

    for(i=0;i<9;i++)
    {
    if (a[i]>a[i+1])
        
        *min=a[i+1];
        
        else
        {a[i+1]=a[i];
        *min=a[i+1];}
    }
        puts("The min you want is:");
    printf("%d\n",*min);
   
    return 0;
   
    }
