我在Ubuntu中使用apt-get 安装了Clang,我可以使用它成功编译C文件.但是,我不知道如何通过它编译C++.编译C++需要做什么？

问题:如何使用gcc编译器编译C++程序？

info.c:

#include<iostream>
using std::cout;
using std::endl;
int main()
{
   #ifdef __cplusplus
   cout << "C++ compiler in use and version is " << __cplusplus << endl;
   #endif
   cout <<"Version is " << __STDC_VERSION__ << endl;
   cout << "Hi" << __FILE__ << __LINE__ << endl;
}

当我尝试编译 info.c

$ gcc info.C

Undefined                       first referenced
