linux c stl入门问题，欢迎帮忙

action08

[shell@localhost op]$ g++ stl.cpp -o op
GCC expected primary-expression before ‘.’ token
..................［N的这种错误］

－－
G的第一条就不是答案，问题真多，但很单一，怎么回事？

建议把代码贴出来

同学,你的函数忘了加"windows.h"了

除了第一个，所有的std都得改成srl吧

还得 include <iostream>

e_sharp

list<string> srl;

后面用的都是 std

应该是缺少头文件#include

写代码仔细一点，你里面的错词到处都是。
给你改了一下：
[/code]
#include <iostream>
#include <list>
#include <string>
#include <unistd.h>
using namespace std;

int main()
{
        string s1 = "hello, world.";
        string s2 = "I am new tester of stl in linux gcc.";
        string s3 = "ok, now to show sm.";
        string s4 = "this is the 4nd string";
        string s5 = "end, bey...";

        string sa = "my dog.";
        list<string> srl;


        srl.push_back(s1);
        srl.push_back(s2);
        srl.push_back(sa);
        srl.push_back(s3);
        srl.push_back(s4);
        srl.push_back(s5);

        list<string>::iterator sit;
        sit = srl.begin();

        for(; sit != srl.end(); ++sit)
        {cout<<"the size"<<*sit<<endl;

                if(*sit == "my dog.")
                {cout<<"\tshall deletc: "<<*sit<<endl;
                        sit=srl.erase(sit);
                        cout<<"\tthe size = "<<srl.size()<<endl;
                }

        }
        cout<<"proc shall exit."<<endl;

                sleep(100);

        return 0;
}
