A closer look, however, suggests that a rules-based approach is superior. 1  A good monetary policy rule specifies a plan of action which the central bank cannot later ignore, while discretion allows central bankers to reactâand often overreactâto economic indicators as they see fit.
A syntax error is an error in commands. For example, the following command: dir (path) which displays a directory in a Windows Command Prompt. The following, dir c:/windows/system32 would show the contents of the Windows/system32 directory in the C: drive.
If you constrain your type, also, you will get compiler errors immediately if you attempt to use a type that doesnât meet the constraint. This tends to be much clearer than the syntax error you would get within C++ template code itself when you used a type not supported by a C++ template.
