16 New FAQs:

• [4.37] What updates were made for the 05/02 release?
  (created)
• [5.6] Wait a minute, does that previous FAQ say to not answer their question just because it's already answered in the FAQ?!?
  (created)
• [15.17] How can I tell {if a key, which key} was pressed before the user presses the ENTER key?
  (inspired by a posting by Alan Didey)
• [15.18] How can I make it so keys pressed by users are not echoed on the screen?
  (created)
• [15.19] How can I move the cursor around on the screen?
  (created)
• [26.1] Can sizeof(char) be 2 on some machines? For example, what about double-byte characters?
  (inspired by Randy Sherman)
• [26.2] What are the units of sizeof?
  (inspired by Randy Sherman)
• [26.3] Whoa, but what about machines or compilers that support multibyte characters. Are you saying that a "character" and a char might be different?!?
  (inspired by Randy Sherman)
• [26.4] But, but, but what about machines where a char has more than 8 bits? Surely you're not saying a C++ byte might have more than 8 bits, are you?!?
  (created thanks to Randy Sherman)
• [26.5] Okay, I could imagine a machine with 9-bit bytes. But surely not 16-bit bytes or 32-bit bytes, right?
  (created thanks to Randy Sherman)
• [26.6] I'm sooooo confused. Would you please go over the rules about bytes, chars, and characters one more time?
  (created thanks to Randy Sherman)
• [26.7] What is a "POD type"?
  (created)
• [26.8] When initializing non-static data members of built-in / intrinsic / primitive types, should I use the "initialization list" or assignment?
  (created)
• [26.9] When initializing static data members of built-in / intrinsic / primitive types, should I worry about the "static initialization order fiasco"?
  (created)
• [26.10] Can I define an operator overload that works with built-in / intrinsic / primitive types?
  (created)
• [26.11] When I delete an array of some built-in / intrinsic / primitive type, why can't I just say delete a instead of delete[] a?
  (created)

5 Changed FAQs:

• [6.14] What are some "interview questions" I could ask that would let me know if candidates really know their stuff?
  (rewrote from scratch thanks to Robin)
• [7.6] How can I prevent other programmers from violating encapsulation by seeing the private parts of my class?
  (minor rewording)
• [11.14] Is there a way to force new to allocate memory from a specific memory area?
  (two typos ("myPool" vs. "pool") in the code were fixed thanks to Randy Sherman)
• [32.3] How can I include a non-system C header file in my C++ code?
  (fixed a grammatical error in the first paragraph thanks to Randy Sherman)
• [38.13] Is it possible to convert C++ to C?
  (added a URL for Cfront and reworded the third bullet thanks to Richard T. Guy)
