Converting Integers to Hexadecimal Strings in C

In C , converting an integer to a hexadecimal string can be achieved using the header's std::hex manipulator. Printing the converted string can be done through std::cout, while using std::stringstream is an option for capturing the result as a string.

To use std::hex, simply insert it before the integer you want to convert:

std::stringstream stream;
stream 
You can also add prefixes to the hexadecimal representation, such as "0x", by including it in the first insertion:
stream 
Other manipulators of interest are std::oct (octal) and std::dec (decimal).
One potential challenge is ensuring the hexadecimal string has a consistent number of digits. To address this, you can use std::setfill and std::setw:
stream 
Finally, here's a suggested function for converting integers to hexadecimal strings:
template
std::string int_to_hex(T i)
{
  std::stringstream stream;
  stream
