10) What will be the printed values of x, y and z

x = 10;                                                          Change (a  IN, b IN  OUT,  c OUT)          

y = 5;                                                             {

z = 8;                                                                     a = 100;

Change (x, y, z);                                     b = 200;

Print (x, y, z);                                                  c = 300;

11) Make up three questions in Unity 3D that has nothing to do with the questions I asked. Answer the questions ?

c) Fixed Update ()

Resources

d) Update ()

Step

e) Start ()

Create

f) Scripts

Function for Rigid Bodies

Explanation / Answer

Sol:

=======================================================

1)

room - scene

events/action - update()

paint - update()

resources - project view

step - start()

create - script

function with rigid body - fixed update()

2)

d) Open Source for creating Animations

g) Usability software (HCI), to understand  end-user

3)java application - compilation

c# - compilation

c++ - compilation

java applet - compilation with interpretation

very portable - compilation

fast to develop/test - interpreted

fast to execute - compiler

less secure - interpreted

Source Code must reside on client Machine - compilation

generate a true .EXE - compilation

requires virtual machine to execute - compilation

HTML - interpreted

4)

Putting Sensors on animal to obtain its movement - motion caption animation

Equivalent to moving all objects on the screen - morphing

Oldest type of Animation - moving camera

More applicable to 2D than 3D - orthographic view

unpredictable behavior of enemy in FPS - artificial intelligence

Objects Farther away appear to be smaller - perspective view

Copy of an object - instance

A dog gradually turning into a Cat - frame by frame animation

Provides re-usability - inheritance

Provides safety - encapsulation

5)

e) Dynamic Variable

d) Static Variable

c) Global Variable

6)

d) Break Point

7)List A or B for the blank spots below

a) parameter passing by value or b) by reference

Java primitives  __________parameter passing by value

Java arrays and other object ______________ by reference

Safer _____________ by reference

Better for Performance  __________________by reference

Equivalent to IN OUT   (returns a value)    __________________parameter passing by value

Equivalent to  IN  (does not return a value) ______________________by reference

8)code not given

9)

The first function or can be say as Entry point of the Java Application is Main() function.

It is the starting point of the programs. The interpreter starts from the main function and go with the flow of the program. main function is needed to be declared as public and static as compulsion to run the code as the cmpiler cant find the main function if it is not declaed as public and static.

10) What will be the printed values of x, y and z

ans) 10, 5, 8  

explanation:note)in - An input Parameter (may not be modified).

out - An output Parameter (may be modified to communicate information to the caller).

inout - An input Parameter that may be modified.

here initially x , y , z has initial values , but these vales is passed to a function and with IN, IN OUT, OUT ,the compiler can decide where reference or copy is a better . so it might modify ot may not , depends on compiler

11) Make up three questions in Unity 3D that has nothing to do with the questions I asked. Answer the questions ?

ans)

1) what is a vertec shader and a pixel shader?

2) is vector normalization mandatory for an object movement?

3)can a thread be modified for a texture?
