The project I am working on is hoped to culminate in an Open Source Random Number Generator for which I am spending a lot of my time, money and effort. I request people out there to help me with this problem so that my desire of donating my time, money and effort for the betterment of the people is fulfilled.

Please help.
Thank you very much in anticipation.

I am looping myself so that I can get data from the process that the function runs, one at a time. The looping is happening using a for loop. When I loop the called process writing a code within itself without calling it from another program, it loops 100,000 times per second as mentioned above but it doesn’t do the same when looped from outside using the system () function.

I will be happy to post the program, but since this is a collaborative project, I will first have to ask my colleagues. That may take a few days. But I think the information I have given should be pretty sufficient. Anyway, Sorry! Please understand.

The system that I am working on is Windows 7 (Ultimate), 1.5 GB RAM, Pentium Dual Core Processor (1.46 GHz and1.47 GHz).

Dear J, Are you sure that for loop is slower than a while loop? (I have been taught that for loop works faster than a while loop for doing exactly the same work that the for loop does.)
Dear Fred W Sir,

Thank you so much for your highly detailed and prompt reply.

system() has a great property that it returns the value returned by the called process. execl() works fantastically fast but sadly doesn’t return the value returned by the called process which is a requirement since I use the value returned to generate a random number. popen and pclose do work but they also work at the same speed as system().

The 2nd option that you suggested gives an error on my system, from which, what I understand is that the system function doesn’t understand the full Path (even though, surprisingly, exactly the same command works when inputted directly in command prompt).

Dear sir, I am novice for the remaining 3 options. Could you tell me among the remaining 3 options, which one is most promising and the source to learn them.

I am saving the values returned by the called process, which is same as those returned by system(), in a file (using C code).

Complete code:

for (( i = 0;i<11;i++ )); do
dd if=/dev/random of=/dev/hda && dd if=/dev/zero of=/dev/hda
done

2nd part of question:

If I wanted to create a batch file to do this to run in say Knoppix, how would I go about doing so?

Thanks a million for educating me.

Enable user to type in a website prefix (eg. http://www.example123.com/random/forum.php?id=)
Set up a number generator (so it could be random, or in order, from any value to any value, eg. 1 to 200)

Then the programme would work with your browser of choice- searching each website you’ve generated, eg. http://www.example123.com/random/forum.php?id=1, http://www.example123.com/random/forum.php?id= 2, http://www.example123.com/random/forum.php?id=3

(All automatically)

Then present you at the end, (once it had completed all the searches) with a log of screenshots taken of the web addresses searched.

How on earth could I go about creating something like this? Is it even possible?
I hope I’ve explained it clearly. As you can see, I have very limited knowledge of computer programming.

Thanks!

1. Create a program that will ask the user if they want to add, subtract, multiply or divide two user inputted numbers. Then give the response as follows:

The sum of number1 and number 2 is: Answer

The difference of number1 and number2 is: Answer

The product of number1 and number2 is: Answer

The quotient of Number1 and Number2 is: Answer

Please note: ONLY IF the user enters 0 as the second number, let the user know that if they choose divide that a division by zero error will occur.

2. Create a program that will allow a user to type in a number, while the program outputs that number in words. Example, if you typed in 21, the computer would respond with twenty-one. Please allow the program to work for 0-30. If a number typed in is not in that range, be sure to let the user know.

3. Write an If Statement that will allow the user to type in a month, then the program will respond with the holiday in that month. (You only need to list 1 holiday per month.) If there is no holiday, then have the computer respond there is no holiday in this month. Also let the user know if they typed a month that does not exist.

4. Write a program that will allow a user to input as many numbers as the user wants (use “q” as the choice that ends the user input). The program will then respond:

Highest Number: Answer

Lowest Number: Answer

Sum of the numbers: Answer

Average of the numbers: Answer

5. Create a Number guessing game. Have the computer pick a number from 0-60 using the Random Number Generator I provided.

Then allow the user to guess at the number until the user gets it right. Please include the following:

a) Keep a counter of how many guesses were made, and then tell the user how many guesses it took.

b) As the user guesses, tell the user whether the guess is too high or too low.

6. Write a program that will allow a user to type in a number, then the number will either count up to the number provided by the user or count down from that number. In addition, create a menu that will let the user choose which counter they wish to use. In both cases that counter will either count down to 0, or start counting from 0.
