Class object construction process

[humble_learner]

#include "stdafx.h"
int func1()
{
	printf("Initializing i\n");
	return 10;

}
int func2()
{
	printf("Initializing j\n");
	return 20;
}
class A
{
private :

	 int j;
	 int i;
public:
	A():i(func1()),j(func2())
	{
	}

};

int _tmain(int argc, _TCHAR* argv[])
{
	A a;
	return 0;
}

What is it that causes func2() to be called before func1() in the above sample ? Is this as per the C++ specification ?
Can you please outline the process of execution of the constructor and creation of data members during object construction ?
