就这么一个简单的屏幕输出，提示了一大串的错误提示：
#include <iostream>
#include <string>
using namespace std;

int main()

{

cout << "Fucj";

return 0;

}
错误提示类似以下，还有很多，截取一部分。我怀疑是库文件又问题，但是又不知道问题在哪里：

有点迷糊，能不能解释一下

重點在於.....跑起來一切正常阿.
ifg@ubuntu:/tmp/c$ g++ -o test test.c
看看你是不是用錯compiler了?

我是用g++的，版本应该是：4.0.2。
查它的版本是什么时候的用什么命令参数阿？？

兄台：你的问题十分没问题。

$ g++ -o test test.cpp
$ ls
test test.cpp
$ ./test
Fucj$

查它的版本是什么时候的用： g++ -v
$ g++ -v
