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.
Syntax errors are errors in your code such as a missing semi-colon. Run time errors are errors that appear during run time such as an infinite loop. Logic errors appear when your code does not do what you want it to do because of the logic such as the comparisons are wrong.
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.
