difference between structures and clas...

Ans:

Structs are value-type variables and are thus saved on the stack, additional overhead but faster retrieval.  Another difference is that structs cannot inherit.

U can inherit structure. And the default inheritence is public whereas in class the default inheritence is private

There is only one difference between struct & class in 'C++'..  All the variables/functions in struct are 'public' and in class they are 'private' by default.  This is a very common misconception even among experienced Software engineers.

There is not just a one difference. Differences are many like
The structure are uses stack and class uses heap memory.
The structure cannot use pointers while class can.
The strucure may not have private.
You can not define object of structure while you can define object of class.
Class is a blue print, while structure is actual data.

class does not occupy any memory until we are not going to define any object for that class.
In other way class are the blue print and object are the real time entity or instance of the class which is occupying the memory.

Class are other features like abstraction , encapsulation , polymorphism which are not implemented by structure.

Amid, you are talking about "C" structure that knows nothing about classes etc. The only difference between C++ class and struct is default access specifier (private and public respectively)

There are a lot of differences between Structure & Class in C.
But in C++ the only difference is the members structure are by default public where as class members are by default private.
Using C++ structure we can do the OOPS concepts like inheritance
