Look in the runtime/Cpp/demo folder for a simple example. Putting it all together to get a working parser is really easy. How do I run the generated lexer and/or parser?

Should work out of the box without any additional dependency. Just use the provided projects for XCode or Visual Studio and build it. Instead of downloading a prebuilt binary you can also easily build your own library on OSX or Windows. Use CMake to build a Linux library (works also on OSX, however not for the iOS library). Prebuilt C++ runtime binaries for Windows (Visual Studio 2013/2015), OSX/macOS and iOS are available on the ANTLR web site: Once you've generated the lexer and/or parser code, you need to download or build the runtime.

MyGrammarBaseListener.h + MyGrammarBaseListener.cpp.

MyGrammarListener.h + MyGrammarListener.cpp.

MyGrammarBaseVisitor.h + MyGrammarBaseVisitor.cpp.

MyGrammarVisitor.h + MyGrammarVisitor.cpp.

MyGrammarParser.h + MyGrammarParser.cpp.

If visitor or listener are not suppressed (which is the default) you'll get:

You will see that there are a whole bunch of files generated by this call.
