void main(){
int x=1;
printf("%d\n",x=2);
}

You're the faggot that is going off topic by talking about unrelated stuff such as variables at block scope. Also,

I've already said everything I had to say. All that's left is for you to acquire at least a fifth grade reading level.

You still haven't explained how having variables at block scope level supports 'global variables have static duration'.
