Explanation:
Detailed explanation-1: -In computer processors, the overflow flag (sometimes called the V flag) is usually a single bit in a system status register used to indicate when an arithmetic overflow has occurred in an operation, indicating that the signed two’s-complement result would not fit in the number of bits used for the result.
Detailed explanation-2: -Overflow is set when the result of an signed arithmetic operation is too large to fit in the destination.
Detailed explanation-3: -Direction flag is used in string operations and interrupt flag is used to enable the interrupts.
