How do I add new downlaoded header files to codeblocks?

[JaydenFernandez]

I want to add std_lib_facilities.h to codeblocks, but I don't know where to put it.  Even if I think I placed it in the right folder, it still returns a 'fatal error' because it can't locate the header file, when I include it in my program.

I also want seed_randint() to be a function in my program, but it doesn't show up in scope, so I need to download a header file for that too.
