Thanks for all your good advice, but the function that takes a structure containing that generic pointer already exists. It's one of a library functions that I'm trying to use. So I cannot change...

Hello,
I have a rather complicated pointer/syntax problem. One of my function arguments is a pointer to a structure which contains a void pointer. If I point the pointer to a scalar then in my...

Hello,
I am trying to make one patch transparent.
What the documentation says about making only the specified object transparent is this:
"alpha(object_handle,value) sets the transparency...

I can see it now. Thank you for the explanation.

I see. It's confusing having k=k/2 written that way.

But then why do you say it will function once? If we start from positive p and keep halving it, we would never reach a value <= 0, so it would...

Hello,
Could you explain me what this statement means? I am confused with k/=2 as iteration statement.

for (int k = p; k > 0; k /= 2)

Thanks

Hello,
I coded binary and Fibonacci search algorithms in Fortran and was trying to determine for what size of array Fibonacci search would become faster than the binary search. Unfortunately, what I...

Thanks. This helped a lot. The program works fine now :)

This is what I get now :(

'Exception in thread "main" java.lang.ClassCastException: AQueue cannot be cast to java.util.ArrayList'

I can cast it to FIFO, which is my interface, and retrieve it...

Thank you very much!

The reason is simple: this is what my assignment brief is telling me to do ;) It says 'This will allow to practice with ArrayList and allow you to use generics, if you wish.'...

Hello,
I created an ArrayList with lists and arrays (randomly chosen) of queues and now need to get access to these lists and arrays to add, remove and display elements in them. How could I do this?...

So the less parameters the better? I thought that it was better to send the arguments which are the same for all subclasses up to their superclass.

Could you also advice me on menu class? I have...

I've tried both these methods before, but they set maxStrength too late. In my subclass I call superclass constructor and one of its parameters is strength, which then is checked in setStrength() and...

Works like this :) Thanks!

Hello,
I am trying to write my first ever assignment in Java and am straggling with it.
I have a superclass LivingThing and two subclasses, Monster and Human. Both subclasses have an attribute...

I'm a woman studying Computer Science. There are more and more of us doing Computing courses :)
I am now learning both, Java and Haskell, and I enjoy them both. Although must admit that I find...

Yes, I did try it and all I got was a compiler error. It doesn't like src += n;

error: invalid operands to binary +

Sorry, but I don't understand this code :( Why do you have to use puts(word) after reading in to word with sscanf? And what does += do?

Hello,
Is there any way of reading words from a string containg a few words separated by white spaces using a loop? I don't know how many argumets the user will input. I wanted to do it like this:
...

Yes, I understand it now. Thank you.

I don't know how many strings I need.

I see. I used an array of strings as you adviced me and it works like this. Thank you.

Yes, I was trying to copy it. Is it fine or should I rather malloc cmd and point it to the input directly...

I thought so, but if I do it as:

cmd[0]="some_string";
cmd[1]="another_string";
etc.

it works fine.

Hello,
I have to write a program using exec() where user can specify the pathname and arguments. I am trying to read in the arguments in the following way:

#include <stdio.h>
#include <unistd.h>...
