关于STL中的list :: sort() [英] About list::sort() in STL
问题描述
你好,
我遇到了一个问题,我无法解决。我用它作为
跟随:
list< longL
for(long i = 1; i< ; = 479250; i ++)
L.push_back(i);
L.size(); //这给了479250;
L.sort();
L.size(); //这里给出20498?
为什么列表中的元素被删除?我无法理解
真的很感谢你的帮助!

Hi there,
I met a problem, which I could not solve. I used it as the
following:
list<longL
for (long i=1;i<=479250; i++)
L.push_back(i);
L.size(); // this gives 479250;
L.sort();
L.size(); // Here it gives 20498?
Why the elements in the list are removed??? I could not understand it
Really appreciate your help!

在g ++ 3.4.4中不会发生。你的平台是什么?请提供
最小*可编辑*(强调可编译)示例,展示有问题的
行为。
谢谢。
Doesn''t happen in g++ 3.4.4. What is your platform? Please provide a
minimal *COMPILABLE* (emphasis on compilable) example that exhibits the
behavior in question.
Thank you.

我使用Visual C ++ 6.0。这是一个我测试的简单例子,它没有工作。
#include< iostream>
#includer< list>
using namespace std;
int main()
{
>
list< longL;
for(long i = 1; i< = 479250; i ++)
L.push_back(i);
cout<< L.size()<< ENDL; //给479250
L.sort();
cout<< L.size()<< ENDL; //给20498; ???
返回0;
}
I use Visual C++ 6.0. Here is a simple example I test, which does not
work.
#include <iostream>
#includer<list>
using namespace std;
int main()
{
list<longL;
for (long i=1;i<=479250; i++)
L.push_back(i);
cout<< L.size()<<endl; // give 479250
L.sort();
cout<< L.size() << endl; // give 20498;???
return 0;
}

使用命名空间std;
int main( )
{
list< longL;
for(long i = 1; i< = 479250; i ++)
L.push_back(i);
cout<< L.size()<< ENDL; //给479250
L.sort();

L.push_back(i);
cout<< L.size()<<endl; // give 479250
L.sort();
cout<< L.size() << endl; // give 20498;???
return 0;
}
之后我使用gcc版本4.1.2将#includer更改为#include它正常工作
。可能
是使用Visual C ++ 6.0的一两个bug。

After I changed the #includer to #include it worked
correctly for me using gcc version 4.1.2. There might
be a bug or two with Visual C++ 6.0.
