仅供参考！谢谢！

#include <stdio.h>
int main(int argc, char *argv[])
{
    char s[81];
    int a[10] = {0};
    scanf("%80s", s);
    for (int i = 0; s[i] != '\0'; i++)
    {
        for (int j = 0; j < 10; j++)
        {
            if (s[i] - '0' == j)
                a[j]++;
        }
    }
    for (int j = 0; j < 10; j++)
    {
        printf("%d:%d次 ", j, a[j]);
        if ((j + 1) % 3 == 0)
            puts("");
    }
    puts("");

    return 0;
}
