What is the difference between carry flag and overflow?

WebCarry In == Carry Out. With two's complement representation the result of addition is correct if the carry into the high order column is the same as the carry out of the high order column. The carry can be one or zero. Overflow is detected by comparing two bits, an easy thing to do with electronics. Here are some more examples: Overflow ...

How do you determine overflow and carry? – ITExpertly.com

WebInteger overflow can be demonstrated through an odometer overflowing, a mechanical version of the phenomenon. All digits are set to the maximum 9 and the next increment of the white digit causes a cascade of carry-over additions setting all digits to 0, but there is no higher digit (1,000,000s digit) to change to a 1, so the counter resets to zero.
