Array and struct initialize in C++

I would like to initilize some elements of an struct and array in C++.

In C you can do:

unsigned char array[30] = {[1] = 4, [20] = 4};
struct mystruct 
{ int i;
  int j;
}
struct mystruct e = {.j = 2};

But I cannot do it in C++. Is there any way to implement this kind of designated initializers?

Its always good to Initialize ALL the element in array or structure to avoid many errors.

Below may help you.

Initialization for struct

struct myStruct

{

   int i;

   int j;

   myStruct()
   {
       j=10; //default Constructor     
   }

};

Initialization for Array:

unsigned char array[5];

array[0]='A';

array[2]='C';

In C++ struct has constructors (just like class), so you could always init your var in them.
