   3 dni temu · A constexpr function is a function whose return value must be computable at compile-time when required. Because of this, constexpr functions can be used in constant expressions. To make a function a constexpr function, we simply use the constexpr keyword in front of the function’s return type.

   4 dni temu · Return by reference returns a reference that is bound to the object being returned, which avoids making a copy of the return value. To return by reference, we simply define the return value of the function to be a reference type:

   3 dni temu · Alex September 11, 2023, 3:46 pm May 28, 2024. An object of type std::array can be passed to a function just like any other object. That means if we pass a std::array by value, an expensive copy will be made. Therefore, we typically pass std::array by (const) reference to avoid such copies.

   2 dni temu · In this explainer, we will learn how to find the absolute maximum and minimum values of a function over a given interval using derivatives. We can use the derivative of a function at a point to help us determine what happens to that function locally. For example, we know that the local extrema of a function must occur at its critical points.
