I am not able to run the code in C++

[arpitomar]

What should I do after that command? And In what folder I should save C++ Example and it runs easily?

When I run C++ code, the above error shows in visual studio code.

@arpitomar your build command in VSCode is missing the path to fcwt.h as I explained in #39 as well. Alternatively, it seems you can successfully build the library with cmake. You could add the path to fcwt.h and then link the library into your own project.
