网上关于迭代器出现的问题好少，因此没有头绪

[晨星]

先试试把
using namespace std;
放到所有#include指令之后。

[pengzhixi]

double RR(Job* sequence)
{
list<Job> queue;
vector<Job> list(&sequence[0],&sequence[SIZE]);//修改的地方

double SJFNonpreemptive(Job* sequence)
{

vector<Job> waiting;
vector<Job> list(&sequence[0],&sequence[SIZE]);//修改的地方

谢谢你啊，我学的还是不扎实，呵呵。
