C#

Question

Hi Everyone,

Below are the few questions in which i found difficulty :-

Q.1) Program in which we apply partial in interface?
Q.2) Why foreach loops are preffered over for loops?
Q.3) why "public static" is necessary in operator overloading?
Q.4) why interface support multiple inheritance whereas classes are
not ? Cant we do explicit implementation in classes?

Thanks and Regards
