Return an array which is iniated in a one liner

Question

I want to return an array of my custom structure object timeInDay with as few lines as possible, in order to return a day in my time schedule.

struct timeInDay[] getRingTimesForWeekDay(int day) {
  switch (day) {
    case MONDAY:    return { {7, 50} };
    case TUESDAY:   return { {7, 50} };
    case WEDNESDAY: return { {7, 20} };
    case THURSDAY:  return { {7, 50} };
    case FRIDAY:    return { {7, 50} };
    case SATURDAY:  return { {7, 50} };
    case SUNDAY:    return { {7, 50} };
  }
}
struct timeInDay {
  unsigned short hour;
  unsigned short minute;
};

Right now it produces an error with the return value of the method:

error: decomposition declaration cannot be declared with type 'timeInDay'
 struct timeInDay[] getRingTimesForWeekDay(int day) {

Would be deeply appreciated if anybody could write down their way of doing it with as few lines as possible.

Answer 1

No line is required to return a c-array from a function, because you cannot return a c-array from a function.

You could dynamically allocate it and return a pointer to first element and size, but you better stay away from that in favor of std::array:

#include <array>

struct timeInDay {
  unsigned short hour;
  unsigned short minute;
};

std::array<timeInDay,1> getRingTimesForWeekDay(int day) {
  switch (day) {
    case 1:    return { {7, 50} };
    default:   return { {7, 50} };
  }
}

However, as others have mentioned already, the function does only return a single element, so it isnt clear why you want an array in the first place.

PS: If the size of the array is dynamic, use std::vector
