If A = {all books in your library} and B = {all books}, which one of the following is true?

a. A is an element of B


b. B is an element of A


c. A is a proper subset of B


d. B is a proper subset of A

If A = {all books in your library} and B = {all books}, which one of the following is true?
Most certainly C. A is a subset of B because all elements of A are elements of B ("some books" falls under the category of "all books"), and your library does not contain all the books in the world (I hope) so A is a proper subset by definition. Therefore, the answer is C.
Reply:c. A is a subset of B.





An element of A would be one of the books in your library


An element of B would be any book


As all the elements of the set A are also elements of the set B, A is a subset of B.


As there are elements of B which are not also elements of A (i.e. books that aren't in your library), B is not a subset of A.
Reply:C yayayay!!!! i love multiple guess!!!





"element" frequentemente refer to one single solitary value, and most personal libraries contain more than one book
Reply:A is a subset of b
Reply:C. Since both are sets, we wouldn't say "element" to refer to A.

M4a itunes purchased files doesn't show up in windows library ?

These m4a files are protected,when i go into my documents\settings folder in my c drive ,can't convert them to mp3 either when i use program to remove protection from them.i'm using a trial version DRM removal software.

M4a itunes purchased files doesn't show up in windows library ?
You can't convert protected files to mp3. That's why they're called "protected files". But there's a way around this. From itunes take all your m4a files and put them in a new playlist and make a CD. Be sure your settings are set to make an audio CD. After you make the CD you import the CD to itunes but make sure your import settings are set to import using mp3 encoder. Now those m4a files are mp3.
Reply:something is wrong with the program then
Reply:You can not use the DRM protected files on other players. You may find a converter to help you remove protect first, then you can use them as you want.

I am using Borland C++ 5.5 compiler. I wrote the code and I added #include <graphics.h>,an error displayed

The error says" Unable to open %26lt;graphics.h%26gt;". Is there a missed "graphics" library in the Borland compiler?

C++ fstream help?

First off im not even sure if the function im looking for is in the fstream library. What I'm trying to do is make a program that fetches lines from a textfile and writes them to a separat string for each line. Lets say i have a 3 line text file that looks like this





hello


whats up


nose





i want the program to write line 1 "hello" to a string, and line 2 to a different string, and so forth, how would i do this?

C++ fstream help?
Do you want to store each line for later processing, or do you want to just print out what's in the file, one line at a time?
Reply:You would need to declare an array of strings, and read each line into the next index.

Copying music from my computer library to CD-RW.?
i had the same problem when i first installed my cd-rw drive.I found that as soon as i changed from using windows media player to real player the problem stops,definatly try this
Reply:use a CD-R(recordable instead or re-writable)?
Reply:Some CD players won't play RW type of CDs, they will only play R types. There should have been an option at the start that lets you choose if you want to play it on other CD players other than your PC. Try burning a whole lot of songs at the one time onto an R CD, then playing it on another CD player to see if this works.

If we want the random # library function to produce a different seq. of values each time the program is run...

Which of the following should be used?????





a. setenv(rand());


b. fopen(srand());


c. srand(clock());


d. srand(time(NULL));

If we want the random # library function to produce a different seq. of values each time the program is run...
c or d. Whenever you randomize based on the NOW timestamp, you will get a true random number. This is especially true in a multi-processor environment, where you are seeking an array of random numbers, and multiple processes are interrupting your array building procedure.





Good luck and Happy Computing!
Reply:i dont know about c


but d works good
