I have two classes, one for articles and another for the cart. the cart consists of an object-array, filled with articles.
I need to sum up the prices of the articles with a foreach-loop within the constructor. When i write the method (that is probably wrong) within the constructor than its type is not accepted as double. How can i sum ...
I have a class with this constructor:

I need to implement a simple macro that finds the modulo of two numbers on a processor that doesn't have a division operator (think ARM). I could use division by repeated subtraction, but I don't know if this was the most efficient or easiest to work with.
Any suggest...
I've coded a SIC assembler and everything seems to be working fine except for the I/O aspect of it.
I've loaded the object code into memory (converted char format into machine representation), but when I call SICRun(); to execute the code, I get an error stating "devf1 cannot be found".
I know this is related to the input/output devi...
what would be the easiest way to convert an ArrayList of Integers to one int, with the 1st Integer in the list being the 1st number in the int, etc. in Java?
For example an ArrayList of Integers: 1 4 6 7 8 3 8
becomes the int value 1467838

With c-style strings, how do you assign a char to a memory address that a character pointer points to? For example, in the example below, I want to change num to "123456", so I tried to set p to the digit where '0' is located and I try to overwrite it with '4'. Thanks.
#include <stdio.h>
#include <stdlib.h>
int main()

Hi Guys,
We were set an algorithm problem in class today, as a "if you figure out a solution you dont have to do this subject". SO of course, we all thought we will give it a go.
Basically, we were provided a DB of 100 words and 10 categories. There is no match between either the words or the categories. So its basically a list of 100 ...
