Exception Handling Mechanism in C++ ( throwing an exception, the try block, catching an exception )

Exception Handling Mechanism in C++

-> C++ exception handling mechanism is basically built upon 3 keywords namely  try, throw and catch.

-> The keyword try is used to preface a block of statements which may generate exceptions. This block of statement is known as try block.

-> When an exception is detected, it is thrown using throw statement int the try block.

-> A catch block defined by the keyword catch , catches the exception thrown by the throw statement int the try block and handles it appropriately.
          A catch block that catches an exception must immediately follow the try block that throws the exception.
