The original topic got moved, so I'm reposting these here. I wanted to make my own advanced quiz after reading a pretty bad one (apparently the NGRP application quiz, but it itself is wrong in places). Note that I love trick questions and questions relating to code theory - most people know how to program basic PAWN so there's no point testing that. This is more a bit of fun, Slice suggested making a website for it but I've not yet, I may also add a few more questions as I think of them.

1. When including the streamer plugin[№], what licensing restrictions are applied to the rest of your code?
   
   
2. What is the best way of adding a user system to your mode?
   
   
3. Which of the following are valid PAWN keywords: stock, inline, state, char, case, and, *then, const, #elif.
   
   
4. Give two reasons why a macro might be used instead of a function, and two reasons why a function might be more appropriate.
   
   
5. "defined" is a keyword which can be used with what type of statement: "#if" or "if"?
   
   
6. Match following code with their correct descriptors, for example "1a, 2b, 3c". Note that some may be covered by multiple descriptions, in which case choose the most specific:
   
   

   1) pawn Code: #define A 5	a) Conditional
   2) pawn Code: #define B(%0) ((%0) * 42)	b) Operator
   3) pawn Code: a > 5	c) Empty statement
   4) pawn Code: a = 5;	d) Statement
   5) pawn Code: ;	e) Macro
   6) pawn Code: {}	f) State
   7) pawn Code: b * 7	g) Directive
   8) pawn Code: =	h) Expression
   9) pawn Code: <g : g_on>	i) Declaration
   10) pawn Code: #pragma semicolon	j) Definition
   11) pawn Code: new c;	k) Invalid empty statement

   
   
7. What is an API and an ABI?
   
   
8. What do the compiler flags "-d", "-O", and "-a" do?
   
   
9. Describe in detail the difference between these pieces of code:
   
   
   pawn Code:

   enum E_DATA
   {
       E_DATA_A,
       E_DATA_B[4],
       E_DATA_C,
       E_DATA_D
   }
   
   new gData[E_DATA];

   pawn Code:

   #define E_DATA 4
   #define E_DATA_A 0
   #define E_DATA_B 1
   #define E_DATA_C 2
   #define E_DATA_D 3
   
   new gData[E_DATA];

   pawn Code:

   #define E_DATA (e_DATA:7)
   #define E_DATA_A (e_DATA:0)
   #define E_DATA_B (e_DATA:1)
   #define E_DATA_C (e_DATA:5)
   #define E_DATA_D (e_DATA:6)
   
   new gData[E_DATA];

   
   
10. When would "static stock const" be appropriate as a symbol declaration?
    
    
11. What does this code do:
    
    
    pawn Code:

    while (a --> 0)
    {
    }

    
    
12. Iterators in "foreach" use a "linked list" structure - what does this mean?
    
    
13. I wish to run two different pieces of code, each once per second. Should they be combined in to a single timer, run as two separate timers, or done in some other manner? Explain your answer.
    
    
14. pawn Code:

    main()
    {
        new a[] = "hi", b = 42;
        Func(a, b, 7);
    }
    
    Func(a[], &b, c)
    {
        new d = numargs();
        // HERE.
    }

    Describe the current "frame" at the point marked "HERE". Include references to the stack, the heap, and registers.
    
    
15. Write an implementation of "numargs" in pawn.
