int main()
{
unsigned long long sum = 0;
unsigned long long temp;
unsigned long long weight;
int i;
for (i=0; i < 64; i++)
{
temp = pow(2, i);
sum = sum + temp;
}
weight = sum / 25000;
printf("舍罕王应该给予达依尔%llu粒麦子！\n", sum);
printf("如果每25000粒麦子为1kg，那么应该给%llu公斤麦子！\n", weight);
return 0;
}
声明变量的时候sum为什么要加一个=0 sum = sum + temp;
不赋值的话，这句话第一次循环的时候没法进行
