A major drawback of error codes is that they lead to function calls being intertwined with if..else blocks testing for the various error conditions. The result is that program logic is mixed up with error handling. This is not a big issue in the simple example above, but it quickly becomes confusing in real-world code.
Should I use error codes?
For simple things that will always be human-operated error messages without codes are fine. You can say “File not found” without giving it an error code. However, if it might be another computer on the other end then you should give error codes in addition.

Why is error handling important?
Error handling helps in handling both hardware and software errors gracefully and helps execution to resume when interrupted. When it comes to error handling in software, either the programmer develops the necessary codes to handle errors or makes use of software tools to handle the errors.
Are error codes universal?
Short answer – no, it doesn’t exist. Every OS, platform and piece of software pretty much has its own error IDs. These are not synchronized or based on any standard set.
What are exceptions and what are the advantages and disadvantages in comparison to error codes?
error codes. Exceptions separate error-handling code from the normal program flow and thus make the code more readable, robust, and extensible. Throwing an exception is the only clean way to report an error from a constructor. Exceptions are hard to ignore, unlike error codes.
What is the disadvantage of exception handling in C++?
Exception handlers have disadvantages. If a function does not return because it, or some other function it called, threw an exception, data might be left in an inconsistent state. You need to know when an exception might be thrown, and whether the exception might have a bad effect on the program state.
What is error and exception in Java?
Errors mostly occur at runtime that’s they belong to an unchecked type. Exceptions are the problems which can occur at runtime and compile time. It mainly occurs in the code written by the developers. Exceptions are divided into two categories such as checked exceptions and unchecked exceptions.

Exceptions are preferred in modern C++ for the following reasons: An exception forces calling code to recognize an error condition and handle it. Unhandled exceptions stop program execution. An exception jumps to the point in the call stack that can handle the error.
Why is throwing an exception better than returning an error value?
Return codes are more brittle The error is ignored when “returned”, and will possibly explode later (i.e. a NULL pointer). The same problem won’t happen with exception. The error won’t be ignored.

What is meant by error handling?
Error handling refers to the routines in a program that respond to abnormal input or conditions. The quality of such routines is based on the clarity of the error messages and the options given to users for resolving the problem.
