conv.array#1. An lvalue or rvalue of type “array of N T” or “array of unknown bound of T” can be converted to a prvalue of type “pointer to T”. The temporary materialization conversion is applied. The result is a pointer to the first element of the array.

void (*functions[256])(void) //Array of 256 functions without arguments and return value And in another function I want to define it, but there are 256 functions! I could do something like this: struct.functions[0] = function0; struct.functions[1] = function1; struct.functions[2] = function2;

Mar 30, 2011 · The C++ tag on the question was (erroneously) edited in, and right now your answer is the thing keeping the mods from removing the tag again (see Q comments). -- 2) In a C++ answer, I would much prefer to not see a C array. Use std::array or std::vector to demonstrate good coding practices. –

With C++11 you can use this also for arrays of local type, and it's the type safe C++ idiom for finding the number of elements of an array. 5.4 C++11 - C++20 pitfall: Using a constexpr array size function. With C++11 and later, it's natural to implement an array size function as follows:
