What is C++11's approach to exception compatibility?

Can you explain how C++11 improves exception handling?

C++11 introduces several features that enhance exception handling, such as noexcept specifier and improved standard library support.

What is the noexcept specifier?

The noexcept specifier indicates whether a function is allowed to throw exceptions. It helps optimize performance by enabling certain compiler optimizations.

How does noexcept affect exception safety?

Using noexcept can improve exception safety by ensuring that certain functions won't throw, allowing for more predictable behavior during error handling.

Are there any compatibility issues with older C++ standards?

C++11 maintains compatibility with previous standards, but using noexcept may require careful consideration of existing code that relies on exceptions.
