In a program randomly generating 10 000 000 alphanumeric codes of 16
characters in length (Ex.: "ZAZAZAZAZAZAZ156"), what would be an
efficient way to ensure that I do not generate duplicates?
STL set, map?
Could you give me a little code example?
Thank you.

Hi,
I am trying to read in a list of data from a file. Each line has a string in
its first column. This is what i want to read. I could start by saying
char to read in 1000 lines to the array( i think!!).
But I want to use malloc. Each string is at most 50 characters long, and
there may be zero to thousands of lines. How do I actually start the array?
I have seen char **array etc. At first I tried char *array but I think
that gives 50...

Hello,
I have a question about strcmp(). I have four words, who need to be
compared if it were two strings. I tried adding the comparison values
like '(strcmp(w1, w2) + strcmp(w3, w4))', where w1 and w2 make up the
first string and, w3 and w4 make up the second string. I do not want
to allocate memory, then put the words together to create a string
only to facilitate strcmp() comparison.
My question; Does anyone know how to get the...

I have 2 strings, "12/28/2005" and "16:44:54". I need to conatenate them and
convert them to datetime format so I can assign them to a datetime field in a
datarow. The time is now being converted to the date "12/28/2005". and I
don't know how to concatenate them since "+" won't work after I convert them.
Thanks, Alpha

char separator = {','};

Hello All,
I'm trying to clarify how Python avoids byte by byte
string comparisons most of the time. As I understand,
dictionaries keep strings, their keys (hash values),
and caches of their keys. Caching keys helps to avoid
recalculation of a string's hash value. So, when two
strings need to be compared, only their cached keys
are compared, which improves performance as there is
no need for byte by byte comparison.

Hello,
I wrote the tiny progam below just to understand arrays and strings
better.
I have 2 questions about arrays and strings in C.
1. Why is it that when you want to assign a string to an character array
that you must use the strcpy() function?

Hi,
I've always used std::string but I'm having to use a 3rd party library
that returns const char*s. Given:
char* pString1 = "Blah ";
const char* pString2 = "Blah Blah";
How do I append the contents of pString2 to pString? (giving "Blah
Blah Blah")

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
