在做一个习题,要求如下:

我在数字比较小时已经解决了这个问题,可是当整数达到30位时,long long int 已经不能存储,请问有什么解决方法吗?

Using character array processing can increase flexibility;
eg:

char chArr[32] = "12345678912345678912345678912345";//你可以使用比较大的长度
int i = 0, sum = 0;
for(; i < 32; i++)
{
    sum += chArr[i] - '0';
}

用char array

You don’t actually need to store the number itself...

If it were me, I would treat this number as a string.
