C++ Exception Handling
This video explains how run time errors can be solved using Exception Handling Mechanism.
try : A try block identifies a block of code for which particular exceptions will be activated. It's followed by one or more catch blocks.
throw: A program throws an exception when a problem shows up. This is done using a throw keyword.
catch: A program catches an exception with an exception handler at the place in a program where you want to handle the problem. The catch keyword indicates the catching of an exception.
