linux 编译文件mm,Linux编译C++文件，说没有找到头文件，怎么啊？新手，不太会用...

源程序：

#include

int main (int argc,char**argv)

{

cout<

return 0;

}

终端命令：zhaowei@zhaowei-desktop:~$ g++ -c hello.cpp

hello.cpp:1:22: error: iostream.h: No such file or directory

hello.cpp: In function ‘int main(int, char**)’:

hello.cpp:4: error: ‘cout’ was not declared in this scope

hello.cpp:4: error: ‘endl’ was not declared in this scope

zhaowei@zhaowei-desktop:~$

终端命令：(查找标准库头文件)

zhaowei@zhaowei-desktop:~$ locate iostream
