C and C++ / Re: Queueing problems in Data and Structures class [C]
« on: January 26, 2015, 03:51:58 am »
Thank you. I think I slightly understand.  Shouldn't there be factorial in there?

So I need to use a PDF function?
What does M stand for? Exponential?

C and C++ / Queueing problems in Data and Structures class [C]
« on: January 26, 2015, 03:27:31 am »
I don't really understand these, nor how to utilize google for help so if any of you have an idea where to start, I would appreciate it :)

Q1. If an array holding a queue is not considered circular, then each remove operation must shift down every remaining element of a queue.  An alternative method is to postpone shifting until rear equals the last index of the array.  When that situation occurs and an attempt is made to insert an element into the queue, the entire queue is shifted down, so that the first element of the queue is in position 0 of the array.  What are the advantages of this method over performing a shift at each remove operation?  What are the disadvantages?
 
Q2.  Given that jobs are serviced at a rate of 30 jobs per hour, determine the arrival rate in jobs per hour which will achieve the expected queue length to be 9.
 
Q3. Jobs arrive at the rate of 20 jobs per minute, and each job requires 2 seconds of service time, on the average. Determine the average waiting time in the queue. What is the probability that at a given time the system is not empty?
 
Q 4. Given that on the average 2 customers can be serviced per minute, determine the average arrival rate of the customers that achieves the average waiting time in the system (including the service time) to be 5 minutes per customer.

To get the courage to break up with my gf Sabrina, I really want to upgrade to a colored model.

Mine is Walrein.

I want to go with the flow and be popular with all the walrus stuff, but I also want to stand out and be a rebel XD

C and C++ / Re: Free C textbook.

Ya! Feel free to send suggestions.
(we get half a point extra cred for corrections etc XD)

Remember this is class specific though, so a suggestion, rather than correction, may not be applicable.

C and C++ / Free C textbook.
« on: November 24, 2014, 02:58:52 am »
Hey guys, my professor wrote his own textbook for C and I find it very good for beginning/intermediate C programmers.
Some chapters are lacking, but it does an extremely good job compared to other books I've seen.

On Page 437, it talks about Huffman Compression, and i thought it was cool and applicable :)

I don't know a ton but I will do my best.

asm (assembly): basically, the absolutely lowest level programming you can get (other than stabbing it with a needle). Because of this, it isn't exactly 'user friendly'. However, with the costs come great benefits. Assembly can be used for just about anything, limited to the power of the hardware and your imagination. This will be the absolutely fastest for a program to run. (Compiled)

Ti-Basic: Pretty much molded on the BASIC language.  There are high limitations including major loss of speed. Best for math, and games made from it are hackish in general. (run-time)

Ion: Not quite sure. Pretty sure it is just an extra library for you to use (compiled)

Axe: Extremely fast and user friendly language. It is only one level higher than asm, so there is little loss in speed if any.  Axe is mainly only for games, BUT you can include asm code inside it, so you can use it to structure your asm. (compiled)

I could be wrong, but you might be able to do something similar to axe and do:
Code: [Select]
function name(input)
    input
    !if -1 then
        code
    else!if -1 then
        code
    else!if -1 then
        code
    ...
    end
end

I'm back to this project.
I'm currently taking a c programming class, and I realized I could make some serious optimizations to this program.  Now it is (in the long run) much smaller in size. Additionally, any lag from rotation is pretty much undetectable.
