What is the most efficient way to read a bit at a particular position in a byte?

Is there any difference in processing speed if use pointers in function instead of passing by value?

(C++ question) I need to be able make a compiled code (like a .dll?) which other programmers can use on linux, win,, mac, etc. The compiled code would simply do calculations and spit out an answer in memory. I need it to have certain functions that they can easily call …

Are there any other good/reliable hashs which are smaller than MD5 and faster? (for purposes of checking for file corruption - not for security purposes) (preferably 16bit?)

What is the most efficient (fastest) way to load data from a file on HDD to RAM? (which would allow to only load a limited section of that file - eg. load only half of the file etc.)

Hi, I was just wondering if anyone can recommend a easy to use library that will work with DirectX (on top of the back-buffer) for things like creating menus, popups, tickboxes, drop-down boxes, tab-menus, etc..? Thanks in advance.

Is it possible to store data to CPU memory, if so how much memory can I store and how? Say I wanted to store an array, about 6MB in size?

How can I import a font file and get the pixel information of the letters so I can make my own custom text drawing function? I basically have a pixel surface (a 2D array) and I want to draw the text to that array.

Does anyone know of an easy way to get the computer to do separate tasks for each core? Assuming each task has no memory collisions etc. how can I get each core to work on it's own separate block of code?

I'm just curious if anyone knows if there is a ready made function in C++ to sort (numerically or alphabetically) multiple arrays based on a particular array? i.e. Imagine you have multiple arrays or a multi-dimentional array containing data about users (name, age, etc.) Is there a function that for …

Why do some people put main(int argc, char ** argv) not main() ? What's the difference? When is it needed? Thanks in advance, Tom.

Hi, I need to make a video player. I have sequences of image data (bitmaps) which are very large (1920x1080), and need to display them onto the screen at least 60FPS. What is the most efficient way to do this so I won't get loading/displaying delays? PS: I'm thinking to …

I'm using Visual C++ express 2010. Whats wrong with this code: (A video tutorial uses this code and works fine on theirs) #include <iostream> using namespace std; int main(){ string myString = "hello"; cout << myString << endl; return 0; } ??? Says: error C2679: binary '<<' : no operator …

If I don't know the size a string will be, and if that size may change later, and if that string may contain '0' characters, what methods are there to do this? (I would prefer a professional/reliable method if possible)

Hi all, I need to make a windows application nothing fancy - just simple menu etc. However, I also need to be able to draw pixel colors to the screen (perhaps load from a bitmap image). It must be as fast and efficient as possible - and if possible, easy …
