How to Fix: C++ catch blocks - catch exception by value or reference?

When catching exceptions in C++, it is generally recommended to use reference parameters instead of value parameters. This is because passing an exception object by value would involve creating a copy of the object, which could lead to unnecessary memory allocations and potential issues with the original object.

⚠️ Common Causes

• Passing exceptions by value can lead to unnecessary memory allocations.

💡 Conclusion

By using reference parameters when catching exceptions, you can ensure efficient memory management and avoid potential issues with the original exception object.
