title: Unsigned int into a char array. Alternative to itoa?
body: <p>I have a question about unsigned ints.
  I would like to convert my unsigned int into a char array. For that I use itoa. The problem is that itoa works properly with ints, but not with unsigned int (the unsigned int is treaded as a normal int).
  How should I convert unsigned int into a char array?</p>
  
  <p>Thanks in advance for help!</p>
