Transcription: In compilers that conform to the ANSI C++ working paper, the new operator will not return zero if the requested memory cannot be allocated. Instead, an exception will occur. The effect of the exception is to transfer control to an exception handler. The code you see here may replace the two lines of code above. The call of the new operator is in the block of code beginning with the keyword, try. The exception handler is the block of code beginning with the keyword CATCH.
