Exercise (5-9): Rewrite the routines day_of_year with pointers instead of indexing. static char daytab[2][13] = { {0, 31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31}, {0, 31, 29, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31} }; /* day_of_year: set day of year from month and day */ int day_of_year(int year, int month, int day) { ...

Hi I am having to run a breadth-first search in Java for an assignment. I have a 5x5 grid of tiles (24 in total - 1 tile is left 'blank'). The point of the search is to rearrange the tiles by moving the 'blank' up, down, left or right to eventually rearrange the tiles into the correct order. To do this search, I have created an Arrayli...
I'm currently beginning to program with Java. I tried to code the sequence in the title as an output in Java, but I'm stuck! I'm experimenting with the for function, any help is welcomed ;) ...
Hi Guys, I'm trying to get my head round this mind boggling stuff they call Database Design without much success, so I'll try to illustrate my problem with an example. I am using MySQL and here is my question: Say I want to create a database to hold my DVD collection. I have the following information that I want to include: Film Tit...

Hi There Does anyone know the major differences between the Java and C# garbage collectors? A web search has not revealed much, and it was a question that came up in a test. Thanks, Mike ...
Hi, I'm sure this is a very simple question! I have a Java method in which I'm summing a set of numbers. However, I want any negatives numbers to be treated as positives. So (1)+(2)+(1)+(-1) should equal 5. I'm sure there is very easy way of doing this - I just don't know how!! Any tips would be much appreciated. ...
Updated: EDIT! I have coded the program wrongly. Instead of returning the Fibonacci numbers between a range (ie. startNumber 1, endNumber 20 should = only those numbers between 1 & 20), I have written for the program to display all Fibonacci numbers between a range (ie. startNumber 1, endNumber 20 displays = First 20 Fibonacci numbers). ...
procedure DoSomething(a_1, ... a_n) p = a_1 for i = 2 to n temp = p for j = 1 to a_i p = p * temp DoSomething(10,2,2,2) We are getting mixed results. One of us got 10^7, the other 10^27. I Think I found my error... I keep substituting 10 for p every time, instead of the new value for temp. EDIT: here's my work: {10, 2, 2, ...
Does anyone know of an algorithm to find if a linked list loops on itself using only two variables to traverse the list. Say you have a linked list of objects, it doesn't matter what type of object. I have a pointer to the head of the linked list in one variable and I am only given one other variable to traverse the list with. So my...

A recent homework assignment I have received asks us to take expressions which could create a loss of precision when performed in the computer, and alter them so that this loss is avoided. Unfortunately, the directions for doing this haven't been made very clear. From watching various examples being performed, I know that there are cert...
Write a program that sums the sequence of integers as well as the smallest in the sequence. Assume that the first integer read with scanf specifies the number of values remaining to be entered. For example the sequence entered: Input: 5 100 350 400 550 678 Output: The sum of the sequence of integers is: 2078 ...
For my theory of computing languages class, we got a homework assignment to implement a piece of code in a language that only has while statements for flow control (no if statements). This is mainly to prove that you can write a Turing-complete language with only a while loop. For those of you who can understand language grammars, here...
