I am using a MacBook Air M2, and I am new this machine. I found out that there is Clang on MacBook which is directly taken in use by default for C and C++ code in MacBook. But my system is having one issue or kind of issue, when I compile code with a simple line like:

gcc 1931D.cpp -o 1931D

它给我留下了一个错误:

但是,当我使用以下代码时,它会进行罚款,因为我指的是C++文档,我是猜测。

gcc 1931D.cpp -o 1931D -lstdc++

我的PC为什么会发生这种情况? 是否有办法避免这种情况?

另外,我如何在MacBook Air M2中重新确定整个C++或汇编者?

I Trial gcc 1931D.cpp -o 1931D -lstdc++, and it s working penalty, but, why do I must written “-lstdc++”? 它还在使用视觉演播室法和使用C++推广法方面造成了问题。
