According to the C++23 standard, what is the output of this program? 

    #include <iostream>
#include <typeinfo>

void takes_pointer(int* pointer) {
  if (typeid(pointer) == typeid(int[])) std::cout << 'a';
  if (typeid(pointer) == typeid(int*)) std::cout << 'p';
}

void takes_array(int array[]) {
  if (typeid(array) == typeid(int[])) std::cout << 'a';
  if (typeid(array) == typeid(int*)) std::cout << 'p';
}

int main() {
  int* pointer = nullptr;
  int array[1];

  takes_pointer(array);
  takes_array(pointer);

  std::cout << (typeid(int*) == typeid(int[]));
}
