CentOS中C++的header头文件在哪个目录

• Overview

Partly by convention and partly by design, C programs are split into source files that describe the functionality of the program itself and header files that describe how to invoke that functionality from other source files.

• Location

headers are in /usr/include;

binary files are in /lib
