    Look at an ascii chart-- the letters 'A' - 'Z' have decimal values of 65 - 90. So just generate a random number between 0 and 26 then add 65. So just generate a random number between 0 and 26 then add 65.

    EMU8086 does not have random number generator. Classical method for computing pseudo random numbers is the linear congruential random number generation method by Lehmer, where a new rnz is given by z(k+1) = (a*z(k) + b) mod m. For you are restricted to 16 bit registers ax, bx etc. I show you a 16 bit Lehmer generator: z = (31*z+13)%19683.

    Then it does a randomize, because you'll notice there are 3 or 4 possibilities for each letter to be altered to. That way D isn't always |), it can be |] also, so we grab a random number within our "letter range" of the array. Then basically we maintain a variable that we just add our information to the end of.

    End Function. Private Function ZerotoNine() As String. ' Numbers. Chr(48 + Rnd() * 862150000 Mod 10) 'produces 0-9. End Function. Hi, Quick question (this is not homework by the way)the above code does as it says.produces a to z and 0 to 9 but I'd like to combine both so that it will output a to 9.

  6. C++ Book Sorting Program - Will not sort ... | DaniWeb

    books[i]=GetBook(); SortBookPrice(books, NUMBER); OutputBooks(books, NUMBER); SortBookTitle(books, NUMBER); OutputBooks(books, NUMBER); } So, it sorts the books by price just fine, but I cannot get it to sort the books by title. I am most likely over thinking this, but I've spent a couple hours trying to figure it out.

    hi, i had a few unix questions that I am not sure about the answers. if anybody can give a try... that would be great. 1. In sed, when you do pattern matching, the largest pattern is always matched first, left to right. True or False. 2. The command tr 'a-z' 'A-Z' | tr 'A-Z' 'a-z'. after the command is run, case of the input stream will be swapped.

  8. c++ - std::vector access violation on push_back | DaniWeb

    www.daniweb.com/programming/software-development/threads/445057

    two calls to the above function succeed, and the third creates the longest vector (4 items), and on the fourth call to push_back, somewhere deep within the resize, a call to _Orphan_all () causes an access violation (stack trace in OP) but I can give you the snippet that actually fails. Well, the vector itself is a local variable, so that helps.
