c语言代码解决问题

解题思路:

注意事项:

参考代码:

#include<stdio.h>

#include<stdlib.h>

int compare(const void* a, const void* b)

{

    int num_a = *(int*)a;

    int num_b = *(int*)b;

    if (num_a < num_b)

        return -1;

    else if (num_a > num_b)

        return 1;

    else

        return 0;

}

int main()

{

    int n, i, a[500], b[500],j=0;

    scanf("%d", &n);

    for (i = 0; i < n; i++)

    {

        scanf("%d", &a[i]);

        if (a[i] % 2 != 0)

            b[j++] = a[i];

    }

    qsort(b, j, sizeof(int), compare);

    for (i = 0; i < j; i++)

    {

        if (i < j - 1)

        {

            printf("%d,", b[i]);

        }

        else

            printf("%d", b[i]);

    }

    return 0;

}
