WebNegative numbers can be assigned to char variables. To assign negative numbers “signed” type qualifier is used. I believe most compilers use signed char by default. To retrieve the negative number assigned a simple printf statement with integer format specifier (%d) will suffice. Example : signed char a = -46; printf (“%d”,a); // prints: -46 Most compilers choose to interpret >> on signed numbers to be arithmetic shift. Thus since the number is initially negative (i.e. the MSB bit is 1), after a right shift, that bit is replaced by another 1 to preserve the sign, ergo you end up with -1 as you started.
