int main()
{
    int n;
    int i;
    scanf("%d", &n);

    if (n >= 0) {
        while (n > 0)
        {
            i = n % 10;
            if (i != 0) {
                printf("%d", i);
            }
            n /= 10;
        }
    }
    else
    {
            n = abs(n);
            printf("-");
        while (n > 0) {
            i = n % 10;

if (i != 0){                printf("%d", i);
}

@Hiris 原来我把0全给去掉了，感谢指出的错误

int main()
{
    int n;
    int i;
    scanf("%d", &n);
    if (n % 10 == 0)
    {
        n = n / 10;
    }
    if (n >= 0) {
        while (n > 0)
        {
            i = n % 10;
            printf("%d", i);
            n /= 10;
        }
    }
    else
    {
            n = abs(n);
            printf("-");
        while (n > 0) {
            i = n % 10;
            printf("%d", i);
            n /= 10;
        }
    }

    return 0;
}

@Hiris 改了一下，还是80
