What's with That error? I couldn't get rid of it. As long as my codes increase, The chance of getting that error increasing as well.
The same error;
file:.....\istype.c
Line: 56 and then 68 (Always both line)
Expression:(unsigned)(c+1)<=256
It seems that I assigned an element whose ASCII number exceeds 256 into a char variable. At least, I think so.
