Question
In my technical interview in Robert Bosch they asked  me this question.
int a;
is this a declaration or definition ?
i said it is a definition because memory is allocated  to it & some garbage value is asssinged to it.But he said it is wrong.
if it is a declaration please tell me how it is?

Answer
It is both a declaration and definition.
Nothing is assigned to it. That's why you see some garbage when you print the value.
In case of variables, "extern int i;" is the only place where it is declared, but not defined.
In all other cases it is both declared and defined.
