what would be the output of the following prog? Justify
your answer?
main()
{
unsigned char ch;
unsigned char i;
ch = -255;
printf("%d",ch);
i = -1;
printf("%d",i);
}
Answer Posted / bittu
1255
this is because -255 (00000001) when considered unsigned
looks like 1(00000001) in binary and -1(11111111) when
considered unsigned looks like 255(11111111) in binary
(11111111).
