Why did C++ creators used the same symbol for references and address of operator. When I was a begineer I found it very difficult to differentiate between the two though the right type could be obtained from the context. Is there any advantage in doing so?

Although later you'll consider that it's not so hard to differentiate from context, this guy is the only one who can give you the best answer:

Is this Stroustroup himself?
Nice picture :D
Yea, it's taken from Bjarne Stroustrup's homepage.
You can take a look in it and maybe you can find the answer.
I have put that as my new wallpaper.
I love you Bjarne :-*!
I never know there are some people actually worshipping him. :D :D :D
It may be confusing, but I don't remember having trouble distinguishing between the two different uses. It's true that something like "void f(int &i)" looks weird when you come from C without references, but then again, the contextual differences are pretty clear though.
He is not worshipping him.. You will find many worshippers though...Quote:

When I first saw that syntax, I thought it was intuitive, but of course I understand that overuse of the same keywords in different contexts, with different meaning, may be confusing.
For example the "static" keyword has at least three meanings (and a new one in C99).
I know two meanings of the static keyword.
1. Life time that of the program.
2. Creation of one instance.
Is Internal Linkage the third one?
This should be in a new thread...
static means "instance-independent" when used with members of a class.
It means "internal storage" when used with data/functions at namespace-scope level... what is funny, because with class data members it has external linkage.
It means "static storage duration" for function's static variables.
Since internal storage data implies static storage duration, you can deem that these two last form of "static" have the same semantics (i.e. "internal storage).
But for a beginner, it is not very intuitive that:
In that code, the two static words have the same "meaning".Code:static int hello()
{
static int k=42;
return ++k;
}
However if the auto keyword was not implicit when declaring variables inside a function, that may seem more intuitive to beginners.
That is why I said that there were three meanings.
