}

希望大神们帮帮忙，跑不对折磨死我了

中间有个put(s[i])是我为了验错加的 没有意义

用字符串函数处理的（忽略文件读写部分）

#include <stdio.h>
#include <string.h>
main()
{
    int i, j, a[10]={21,3,15,35,315,121,31,1,2115,2}, c[10];
    char si[10], sj[10];
    for (i=0; i<10; ++i)
    {
        c[i] = 0;
        sprintf(si, "%d", a[i]);
        for (j=0; j<10; ++j)
        {
            if (j != i)
            {
                sprintf(sj, "%d", a[j]);
                if (strstr(sj,si) != NULL)
                    c[i]++;
            }
        }
    }
    for (i=0; i<10; ++i)
        printf("%6d", a[i]);
    printf("\n");
    for (i=0; i<10; ++i)
        printf("%6d", c[i]);
}

原来是strstr函数，666
