I was wondering if I can do it to convert a two digit int to a char for each digit

for example I have a clock that can go up to 59, I want assign the 5 to ch1 and the 9 to ch2

I was thinking to use bits but considering we are talking about awhole 16bits which int has, it would be hard to get the actual number....

there must be a way in which I treat an int as if it's an array of chars or something...

Hi LL,

Pretty easy, once you know how.  :)

  char Digits[3];
  int  SomeValue;

  Digits[2] = 0;
  Digits[1] = SomeValue % 10;
  SomeValue = SomeValue / 10;
  Digits[0] = SomeValue % 10;

or

  sprintf (Digits, "%2.2d", SomeValue);


Good Luck,
Kent

interesting,
although I just found
itoa(int,string,base) will do the job for me
http://www.cplusplus.com/reference/clibrary/cstdlib/itoa/

but I was actually trying to figure out some way similar to yours,

/clap

Hi LL,

Depending on how finely we slice we slice the subtleties, there are probably a dozen ways to do this in C.
