I am approaching the end of my semester and face the upcoming exams. Obviously most of the work for computing is achieved by doing the homework throughout the semester and learning as you go, which I hasten to add I have done! However, I would also like to perform really well in the exam and demonstrate what I know. Therefore, my question has two parts:

1 - What strategies do you recommend in preparation for these kind of examinations? This may sound a little vague, but what I mean is: hardest topics first, last or mix it up? suggestions for breaking down the structure of a session. Also, any hints for good exam technique would be greatly appreciated, eg. do you do easy questions first or just standard order?

2 - I hope this is not an inappropriate question, but are there collections of questions to practise and, if so, is this ok? For example, things like: write an iterative function that finds the max value in an array, write a recursive function which does y. I would love to be able to just practise basic functions to really drill the concepts into my head.

Thanks very much for your time, guys. I hope that this sort of stuff is not a problem to ask. I really am just looking for pointers from people with experience.

Cheers

Write a Structure named BASE_STRUCT and another structure named DERIVED_STRUCT where DERIVED_STRUCT is a polymorphic object that inherits information from BASE_STRUCT"

Multiple Choice: What is the difference between--
// information about pointers int x[] = {1, 2}, y[] = {3, 4}, *p = x, *q = y;

*p++ = *q++;
p++ = q++;

A) The first line increments the values and copies the values from q to p whereas the second line increments the addresses and assigns the address of q to p

B) The first line copies the values from q to p then increments the address whereas the second line assigns the address of q to p and then increments the address pointed by both pointers.

C) The first line increments the addresses and copies the values from q to p whereas the second line increments the addresses and assigns the address of q to p

D) The first line assigns the value of q to p then increments the values of q and p whereas the second line assigns the address of q to p then increments the address pointed by both pointers.

E) There is no difference

Should we actually write a constructor For Base_struct and then write some code like this.

struct Base_Struct
{
int a;
int b;
string c;
Base_Struct()
{
new Derieved_Struct s;
s.a=a;
s.b=b;
s.c=s;
};
}

struct Base_Struct { int a; int b; string c; Base_Struct() { new Derieved_Struct s; s.a=a; s.b=b; s.c=s; }; }
