Have a go at each of these, they're a good starting point towards problem solving using programming. You can also look at the Guide to programming.

Write a program that displays the largest Fibonacci number less than or equal to a limit supplied to the program on each test run. For example, if the limit is 50, the program should just show 34.

Constraints - you may assume the limit is less than one million.

Run your program on the following three test cases:

Test Input
8
234
876543

Note that username changing is not the best idea, as it can turn confusing. Especially if you change it to something completely unidentifiable, and/or change your avatar at the same time. If you really have to, announce it on the news forum.

Also, don't be worried about these things. They are just a new karma measuring thing.

I would also like to apologize for not informing people of my decision. I promise that if I ever become a forum mod again that I will not repeat these mistakes.

Any who doubt shall die.

 def qsort(L): if L == []: return [] return qsort([x for x in L[1:] if x< L[0]]) + L[0:1] + qsort([x for x in L[1:] if x>=L[0]]) 

If you would like to participate in a 5-week web-based course next term to learn the python programming language and how awesome it is, then sign up for the annual National Computer Science School (NCSS) Challenge. I did it last year and came 6th, along with Ben Trubshaw who came 8th, and others. And I will almost certainly do it again this year.

I think the school will pay the entrance fee, which I will confirm later on, so don't worry about that…

Seriously, Python is awesome, and don't let anyone tell you otherwise. Really. Register at http://challenge.ncss.edu.au/ . I recommend it to all.

Oh, and you don't need to know any programming theory before hand. It'll teach you it all. Questions welcome.

 #include <cstdio> int main() { int number = 0; int number2 = 0; int sumofnumber = 0; int xofnumber = 0; float divideofnumber = 0; printf("Put a number in here!"); scanf("%d", &number); fflush(stdin); printf("Put another number in here!"); scanf("%d", &number2); fflush(stdin); printf("I got the numbers %d and %d!\n", number, number2); sumofnumber = number+number2; printf("The sum of your two numbers is %d!\n", sumofnumber); xofnumber = number * number2; printf("The product of your two numbers is %d!\n", xofnumber); divideofnumber = ((float)number / (float)number2); printf("The division of your two numbers is %10.10f!\n", divideofnumber); scanf("*"); return 0; } 

This is the first exercise which Jackson asked us to do with a few added bits. How do i clear the screen after the user has input the two numbers.

• A Super Prime is a prime number with the additional interesting property that as each digit is removed from the right the number which remains is a prime.

Instructions

The following is a list of Super Primes of length 4:
2333
2339
2393
2399
2939
3119
3137
3733
3739
3793
3797
5939
7193
7331
7333
7393

Instructions

• Write a program that prints all super primes of length 6
• Your output should contain each Super Prime on a line each.
• Output sould be in ascending order.
• No other output should be produced by your program other than the numbers.

If you can use File I/O, output your answer to "primes.txt"

The text is a list of words, separated by at least one spaces, possibly together with some punctuation and/or line breaks. The length of each word corresponds to a digit in the "value", with a word of length 10 corresponding to the digit 0. There is to be a decimal point after the first digit.

For example the phrase "How I need a monkey" has words of length 3, 1, 4, 1 and 6 respectively. This is worth 3.1416 (coincidentally this is pi to 4 decimal places).

You are to write a program which, given such a message, returns its value.

You may assume that there are between two and sixty words in the message, and that no word is longer than ten letters. You may also assume that the input will all be on one line of text, and each word will have at least one letter.

1. I've put up a GUI to-do list on the Todo page. Checkboxen to quickly mark off new and done to do's.
2. The news page is now a page which grabs the most recent forum posts from "News" and throws them up formatted into a clean, neat page.
3. The Front Page grabs the most recent 5 of all forum posts, and the most recent news item from this category and embeds them down the bottom.
4. The Minutes page now has an auto-generated list of the 15 most recently made minutes. It also has a form to create a new minutes page.
5. Site members can now invite other people to join, using this page. You can send off an email to other people (preferably in the computer club) with a custom message, and they'll get a link to a page where they can create an account and be a member.
6. You can check how current members joined the site. Enter their name on the who invited page, and it will tell you how they joined, and who let them (unless they used the password).
7. We can set up a "petition". I'm not too sure it'll be of any use, but it's there (for admin use only) if you want it. An example of a wikidot petition is here: http://noooxml.org/petition.
