In programming, using return values to deal with errors can be tricky. Let's look at some of the main problems.
Confusion: Sometimes, return values aren’t clear. For example, if a function gives back a number and also a special error code, it can be hard to tell what really happened. If a function returns , it might mean something went wrong, but it could also just be a regular number. This makes it tough to know what to do next.
No Consistent Rules: Different ways to handle errors make things complicated. Some functions might return , while others might give back negative numbers or specific error messages. This can lead to misunderstandings and make it take longer to fix problems.
Ignoring Problems: Sometimes, developers might miss error return values. They might focus on getting the program to work instead of making sure it’s strong and reliable. This can cause the application to fail later on.
To fix these issues, one good idea is to use the same method for handling errors throughout the code. Clear explanations of what return values mean can help clear up confusion. Also, using structured ways to handle errors can work well with return values. This makes it easier to manage errors and improve the program's reliability.
