       All of the code within the try
       block is executed repeatedly unless an exception is thrown by
       any of the statements within the block.  If an exception is
       thrown, any remaining code within the try block is skipped and the code in the first
       catch block that receives a type
       matching the type of the thrown exception is executed.  If
       an exception is thrown and no match is found at any point in the
       program, the program calls std::terminate(), which terminates
       execution.
