If I’m given a binary digit say 1101, how will i identify whether it is of the unsigned or signed format?
If it is unsigned, means positive, so 8+4+0+1=13
If it is signed, then by using 2’s complement notation, 1101
should be = -3.
So how do i resolve this discrepancy?
just by looking at binary representtation we cannot .thats why we need to define datatype of variable before storing any data.
so if i right
int x;
x=20;
then the last (most significant bit will be reseverd for sign)
So by defining data type as int x;
Are we defining it to be signed or unsigned?
if we have written int x; then it will be treated as signed int.
but if we explicity mention unsigned int x; then it will treated as unsigned int
