有没有现成的函数可用，很多函数都试过了，还是不行啊

Question

你知道, C++ list 容器, 取最后一条数据的值,是哪个函数吗? 
list<CString>::iterator ii;
int szie = g_Queue.size();
int k =0;
CString str;
for (ii = g_Queue.begin(); ii != g_Queue.end(); ++ii)
{
k++;
if(k==size)
{
str= (CString)*ii;
}
}

Answer 1

Example // list::rbegin/rend#include <iostream>#include <list>using namespace std;int main (){list<int> mylist;for (int i=1; i<=5; i++) mylist.push_back(i);cout << "mylist contains:";list<int>::reverse_iterator rit;for ( rit=mylist.rbegin() ; rit != mylist.rend(); ++rit )cout << " " << *rit;cout << endl;return 0;}Output:mylist contains: 5 4 3 2 1你直接用list<CString>::reverse_iterator rit=g_Queue.rbegin() ;str= (CString)*rit;就可以了

Answer 2

back()函数返回最后一个元素的引用front()函数返回第一个元素的引用
