Given a string variable (form input), how can I determine whether it
represents a valid integer?
is_numeric is true for floats as well as integers, and is_int always
fails on a string.

Hello,
I have a function that does some decoding (same as urldecode in php)
and it returns std::string
std::string urldecode(const char* in, std::size_t length);
so, this function parses input and constructes output char by char. I
tried to use all sorts of direct access to the buffer of std::string to
be returned but it's always slow. It appered that if I dynamically
allocate memory fill it with output, then create std::string from this...

I've tried to make a function that returns the middle of a string. For
example:
strmid("this is a text",6,4); would return "is a".
Here is my code:
char *strmid(char *texte, int depart, int longueur)
{ char *resultat = " ";
char *temporaire = " ";
int nbr;

I have a string with n number of characters. I'm trying to create another string which is exactly 12 characters having leadings zeros and the input string at the end
ex: string1 = "7344", I want to format string1 such that it results another string with string1 at the end and leading zeros in front of it like: "000000007344

Hi
I have a string which is at least 4 characters but can be more which I need
to pad, with zeros, to a full length of 15 after the 3rd charactor.
Eg '1234' to '123000000000004'
How can I do this?
Also how can I truncate this back to 4 or however many charactors (e.g.

I need user defined function that converts string to float in c.
since the library function atof and strtod occupies large space in

How can one format an integer into a hex string with leading zeros? Suppose
an integer is 512 which in Hex is 200. I wish to print the 4-byte integer
as 0200 or even 0x0200. The HEX function doesn't create leading zeros. The
Format function (format(value,"X") doesn't create leading zeros.
I believe there should be a simple way that doesn't involving measuring and
padding the string.

Could someone give a hand on how to handle this issue: I need to find a way
of removing zeros from files names. The zeros in the names are used to sort
the file name, e.g. MAK0080.pci, MAK-0080.pci. What I need to do is to
remove the zeros, so the file names become MAK80.pci o MAK-80.pci. I have
done something in Visual Basic using the Mid() function and going thru the
string removing the zeros. Is there a better way of doing this,...

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,...
