Hello,

Yes, as GumRai wrote, to remove warnings about implicit conversion, you have to do an explicit conversion. An other way :

      printf("Time :%s   i:%i",TimeToString(time[i]),i);
 
Thanks all, I keep the answer from angevoyageur.

If it is not too complicated, can you explain what

%s i:%i

does?

Thanks for that :)

You really would think that by putting % in the reference index, that it would at least give a pointer to that :(
