Because it will not help write a clear program. If we overload sizeof, :?, ::, it will cause a lot of confuse rather than make program more easier to understand.

The restriction is for safety.For example if we overload . operator then we cant access member in normal way for that we have to use ->.

Hi all

Firstof all only . :: and .* operators never be overladed.

Because They take name rather than a value as their socound operand and provide the primary means of reffering to members.Allowing them to be overloaded would lead to subtlety.

In order to avoid operator ambiguity :? :: . operators are not overloaded.
