Re: some puzzled questions

1-my first question was not mean that i need to
initialise before main. that is before main is called
by OS.
2-this question does not mean scope resolution
operator alone it means all other operators which
can't be overloaded.


3-one possible way to calulate size of integer is like
try the folowing code 

void main()
{
	int i = 1;
	int j=0;
	while(i)
	{
		i = i<<1;
		j++;
	}
        j=j/8;
	printf("sizeof(int) = %d\n",j);
}


not to achive some thing. i found this questions in an
interview.
