If a reference must always be initialized, then isn't A also true? References within functions must always be initialized because references must always be initialized.

It will be compilation error if you don't initialize the reference at the point of declaration. for e.g

int main(void)
{
int a =11;
int &b;
}
The above code wont compile unless we put the statement as int &b =a; instead of int &b;

Its not necessary let it print garbage value.

Because if we will not initialize the reference, it will take garbage value.
