Ok here are some more questions:

1)What would the program print:

Define Number=2+2

.

.

.

Printf(“the number: %d”, Number*2)

2)

What is wrong in this code:

Class A

{

int function1();}

Struct B

{int function2();}

Main

{

A Aobj = new A;

B Bobj = new B;

A.function1;

B.function2;

}

I just came up with this questions to illustrate a basic mistakes you can run in to while programming, sorry for not writing the all program (could not be bothered), try to figure the principal, let me give you a hint:

For the first question try to think what would the pre compiler do when he see a statement Define.

For the second one try to think about the default state of the attribute of Structure and Class.

Ok, Basically the issue here that Structures are Public by default and Class are Private, so the access to any of the attributes of the class is forbidden.

The precompiler will copy the text as is to all the places where the variable is define therefore the function will print 6 which is 2+2*2
