What are the differences between type traits and type checking in C++?

What are the differences between type traits and type checking in C++?

Type traits are compile-time constructs that provide information about types, while type checking is the process of verifying type correctness during compilation or runtime.

Can you give an example of type traits in C++?

Sure! An example is std::is_integral<T>, which checks if the type T is an integral type at compile time.

How does type checking work in C++?

Type checking in C++ ensures that operations on variables are valid for their types, preventing type errors during compilation.

Are there any performance implications of using type traits?

Using type traits can improve performance by enabling optimizations at compile time, reducing runtime overhead.
