The any () function returns true if any bit of the bitset is 1, otherwise, it returns false. These operators all work with bitsets. They can be described as follows: != returns true if the two bitsets are not equal. == returns true if the two bitsets are equal. &= performs the AND operation on the two bitsets. insurance agents in sarasota
