Join Peggy Fisher for an in-depth discussion in this video Error handling, part of Learning C++ (2014).
…Most programming languages have code that helps handle unexpected errors.…It provides the programmer control over the exception, so…they can provide meaningful messages and avoid program interruption.…In C++, we're going to use the try-catch block.…We place this in our code in areas that might cause an…exception such as trying to read from a file that doesn't exist.…When an error occurs an exception is thrown or…raised, which is then caught by an exception handler.…Here's a simple program that tests to make sure we're not dividing by zero.…
In my program I'm only going to test through one kind…of error, so I have int error code equals 10.…I'm going to ask the user to enter in two…values, one for the numerator and one for the denominator.…Then I want to make sure before I go ahead…and divide that they didn't enter zero for the denominator.…So in my try block I have if denominator is equal…to zero I'm going to stop and throw an error code.…That error code is the code I define at the beginning of the program.…
