Reference

This package adds C++ support to the GNU Compiler Collection. It includes support for most of the current C++ specification, including templates and exception handling。

It can be seen that gcc-c++ provides c++ language feature support for gcc

Actually, in terms of concept,gccrefers to the entire set of gcc tools, which is divided into gcc front-end and gcc back-end (I personally understand it as gcc shell and gcc engine). The gcc front-end corresponds to various specific languages (such as c++ /go, etc.) processing (corresponding syntax checks for specific languages such as c++/go, converting codes in c++/go and other languages into c codes, etc.), the gcc backend correspondingly converts the front-end c code to your computer Hardware-related assembly or machine code, etc. (The description may not be particularly accurate, but that’s the general meaning)

As far as software packages are concerned,gcc.rpm就是那个gcc后端，而gcc-c++.rpmis the gcc front-end for the specific language of c++. This design ensures full flexibility. For different programming languages, you only need to develop different gcc front ends; at the same time, for users, if I only need to support compiling C++, then I will only install one C++ Just use the gcc front-end, and it will not contain program codes with other language features, making the user's software environment relatively lightweight and clean
