adding hpp file?

Question

Visual Studio Code

I downloaded Reed Solomon's code (from here https://github.com/mersinvald/Reed-Solomon) and try to open it, created a project (console) in Visual Studio Community and erased the initial code (from hello world) by changing it to a file in /master/ examples/example1.cpp , and then I try to add other files to the project with includes , but even it does not allow adding .hpp through a new element. But through the existing one, I added it, but the code still has an error that it does not see.
And what kind of file is this? It's just like taking the code to another place?

And what kind of file is this? It's just like taking the code to another place?

Yes exactly. Usually the code is taken out in a couple of cpp and h files. Template code cannot compile in a separate cpp, so cpp and h are merged into one file. Not that something would change on behalf of hpp, it can be renamed to h without any problems.
It does not find the file, most likely because in the original CMake project, the include folder is added to the search path for header files:

#Reed-Solomon/CMakeLists.txt
set(RS_INCLUDE_DIRS ${PROJECT_SOURCE_DIR}/include)
#Reed-Solomon/examples/CMakeLists.txt
include_directories(${RS_INCLUDE_DIRS})

You need to either fix #include "xxx.hpp"to #include "include/xxx.hpp"
Or add a folder in the project properties https://support.pixelink.com/support/solutions/art...
Or use the original CMakeLists.txt as a project file https://docs.microsoft.com/ru- en/cpp/build/cmake-p...
