What are the limitations of constexpr in C++11?
In C++11, constexpr functions can only contain a single return statement and cannot have any side effects.
Can constexpr functions be overloaded?
Yes, you can overload constexpr functions, but the overload resolution rules apply just like with regular functions.
Are there any restrictions on the types of variables used in constexpr?
Yes, only literal types can be used in constexpr functions, which limits the types of variables you can declare.
How does constexpr differ in C++14 and later?
C++14 relaxed some restrictions, allowing more complex statements and multiple return statements in constexpr functions.
