这一段代码提示那么多的警告是怎么回事？没有错误。

#include "stdafx.h"
#include <iostream>
#include <list>
//#include <deque>
#include <string>
using namespace std;


int main(int argc, char* argv[])
{	
	list<string> slist;
	string str;
	cout<<"please enter some strings(Ctrl+Z to end)"<<endl;
	while(cin>>str)
		slist.push_back(str);
	cin.clear();
	cout<<"please enter a string that you want to search "<<endl;
	cin>>str;
	for(list<string>:: iterator iter=slist.begin();iter!=slist.end();iter++)
		if(*iter==str)
		{
			iter=slist.erase(iter);
			--iter;
		}
	//for(iter=slist.begin();iter!=slist.end();iter++)
	//	cout<<*iter<<endl;

	return 0;
}

一边访问slist一边改变slist，运行时会出错滴。。。

identifier was truncated to '255' characters in the debug information

可以无视。说的是调试信息中的标示符被截断了。

[mujiok2003]

可以关闭C4786警告。

vc6.0 的？ 老编译器对stl的支持不足导致的， 尽量还是别用太老的了

是的

最近也遇到这个问题，网上搜的用下面的方法解决了，不知这样对以后的结果有没有影响 问题是因为VC6对STL的一些不完全支持造成，手工屏蔽就可以。 方法为在源文件头部加入一下预编译代码 #ifdef WIN32 #pragma warning (disable: 4514 4786) #endif 问题解决。
