What are advanced type traits in C++?

What are advanced type traits in C++?

Advanced type traits in C++ are templates that provide compile-time information about types, enabling more flexible and safer code.

Can you give me an example of how to use std::enable_if?

Sure! std::enable_if can be used to conditionally enable a function based on a type trait. For example:

#include <type_traits>

template<typename T>
typename std::enable_if<std::is_integral<T>::value, T>::type
add(T a, T b) {
    return a + b;
}

What is the difference between std::is_same and std::is_base_of?

std::is_same checks if two types are exactly the same, while std::is_base_of checks if one type is a base class of another.

How can I create my own type traits?

You can create your own type traits by defining a template struct that inherits from std::true_type or std::false_type based on your conditions.
