and no char*
here's a part of my code:

The current Python standard library provides two cryptographic
hash functions: MD5 and SHA-1 . The authors of MD5 originally
stated:
It is conjectured that it is computationally infeasible to
produce two messages having the same message digest.
That conjecture is false, as demonstrated by Wang, Feng, Lai and
Yu in 2004 . Just recently,...

I'm fairly new to doing involved file i/o and I came across something
weird with a program I'm writing (modifying MIDI data, if it makes any
difference). With some input files, when I modify data and then output
to a new file, the program will crash. The catch is that when I open up
the output file to see what the program managed to write, it...

Hi,
I'm relatively new with C-programming and even though I've read about
pointers and arrays many times, it's a topic that is a little confusing

I'm trying to use a C++ .lib from C# (I tried the Interop group will no
results).
I have a working wrapper DLL (I can get back simple things like int), but
I'm having issues dealing with an array of bytes.
For example, the .lib contains this function:
int create(int id, int scale, unsigned char *image);
In the wrapper DLL I have this...

I am interested in converting sets of 4 bytes to floats in C++. I have
a library that reads image data and returns the data as an array of
unsigned chars. The image data is stored as 4-byte floats. How can I
convert the sets of 4 bytes to floats?
Thanks,

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it. ...
