1. True or False: When you write an Allegro program, you must include the header file named iostream.
2. True or False: When you write an Allegro program, you must include the header file named allegro.h.
3. True or False: While not required, an optional call to the function named allegro_init can expose additional Allegro capabilities.
4. True or False: After you call the function named install_keyboard, you can use any of the keyboard input routines including operating system calls and C library functions to access the keyboard.
5. True or False: The following function call sets the graphics mode to a full-screen window.
set_gfx_mode(GFX_AUTODETECT_WINDOWED, 320,240,0,0); |
6. True or False: The standard configuration of Allegro supports five alternative graphics modes that behave in different ways.
7. True or False: The call to the textout_ex function shown below draws the text "HELLO WORLD" on a command-line screen similar to the use of a cout statement in standard C++.
textout_ex(screen,//Specify bitmap on the screen
font,//Use a default font
"HELLO WORLD",//Specify the text to display
20,//X-coordinate for text
30,//Y-coordinate for text
makecol(255,255,0),//Color text yellow
makecol( 255,0,0) );//Put red behind text
|
8. True or False: Transparency with regard to text is achieved by setting either or both of the color parameters in a call to textout_ex to a value of 256.
9. True or False: A call to the readKey function returns the next character from the keyboard buffer in ASCII format.
10. True or False: According to the documentation at allegro.cc, in order to maintain cross-platform compatibility, you must put the macro shown below at the very end of your main function. This macro requirement is specific to Allegro.
