Array initialization C14

[Rabelo]

hi!

Is there an way of initialize a array of classes with the same object without the need to repeat them?
For exemple:

class myclass
{
   public:
   int first,second third;

  myclass(int pfirst,int psecond,int pthird) : first(pfirst),second(psecond),third(pthird)
  {
  }
};

class myotherclass
{
  public:
  myclass myclassArray[100];

  //--- As far as I know I´d have to initialize all 100 members (with the same values I want exemple (5,7,9) 
  //--- as:

  myotherclass(): myclassArray{{5,7,9},    //   0
                               {5,7,9},    //   1
                               {5,7,9},    //   2
                                ...        //   3,4,5,... 95,96,97  
                               {5,7,9},    //   98
                               {5,7,9}}    //   99
{
}

I want a direct construction type trought an initializer list, without using a for into the boby of myotherclass constructor. Is there an easiest way of doing that?

Thank you

if myclassArray is a vector rather than an array, then you can do it like this

class myClass
{
public:
	int first, second, third;

	myClass(int pfirst, int psecond, int pthird) : first(pfirst), second(psecond), third(pthird) {}
};

class myotherclass
{
public:
	vector<myClass> myClassArray;

	myotherclass() {
		myClassArray.assign(100, {5, 7, 9});
	}
};

Ok 2kaud,

Thank you!!! I will change it to vector.

[wolle]

	myotherclass() {
		myClassArray.assign(100, {5, 7, 9});
	}

As an alternative it's possible to use a constructor of std::vector (that does the same as the assign method) like this,

	myotherclass() : myClassArray(std::move(std::vector<myClass>(100, {5, 7, 9}))) {
	}

Using the std::move function isn't strictly necessary but it should be more efficient (since it avoids the copying of the constructed vector to myClassArray that may otherwise take place).

Yet another option is to not initialize myClassArray in the constructor but by direct assignment like this,

class myotherclass
{
public:
	std::vector<myClass> myClassArray = std::vector<myClass>(100, {5, 7, 9});

	myotherclass() = default;
};

That was exactly what I was looking for!!!

Thank you wolle!!!
