Inforrmation member funtion in C

[sridhard2406]

Hi All,
Could you please anybody tell me, why c structer is not allowing funtion as the one of the member as c++ allows.

Thanks,

Because that is one of the major differencesbetw een C and C++.

C supports data structures, that is user defined types consisting of 1 or more data members.

C++ supports objects, that is user defined types that have 0 or more data members and 2 or more function members. I believe every object must have a constructor of some sort, an assignment operator, if these are not explicitly provided the compiler provides default implementations for you.

Your question is a bit like asking why does a motorcycle have 2 wheels when a car has 4? It is a defining feature of the thing in question.

However, you can have a function pointer as a struct member.

All yuo need do is assign the address of your function to the function pointer in the struct and you can do most of what C++ does.
