Initializing and Constructing Arrays of Objects in C++ -

this question has answer here:

• how use arrays in c++? 5 answers

when declaring array of objects, objects constructed @ initialization, or have constructed after initialization? here example of trying explain:

lets have class:

class object{ public:     int x = 4; }; 

and array:

object objects[8]; 

if access of variables within objects, have construct objects first, or done in array? if did this:

cout << objects[4].x; 

would print out 4?

in c++11 code valid, performs in-class initialization, , indeed, cout << objects[4].x; print out 4. in previous c++ versions (c++98/03), code invalid, , you'd need default constructor initialize variable x, like

class object{ public:     int x;     object(int x = 4): x(x){} }
