2、测试代码hello.cpp：
#include using namespace std; int main() { cout << "Hello world!\n" << endl; return 0; }
3、 gcc hello.cpp -o hello
/tmp/ccTZsfGk.o: In function `main':
hello.cpp:(.text+0x1c): undefined reference to `std::cout'
...........
再看一下man gcc,原来要用g++编译C++程序。

4、g++ hello.cpp -o hello
编译通过，生成hello，运行：./hellow
显示结果：
Hello world!
