#### 15 Aug 2017

**Problem**

You have a numeric value or an enumeration that contains bit flags. You need a method to turn on (set the bit to 1) or turn off (set the bit to 0) one or more of these bit flags. In addition, you also want a method to flip one or more bit flag values; that is, change the bit(s) to their opposite value.

**Solution**

The following method turns one or more bits on:

```
public static int TurnBitOn(int value, int bitToTurnOn)
{
return (value | bitToTurnOn);
}
```

The following method turns one or more bits off:

```
public static int TurnBitOff(int value, int bitToTurnOff)
{
return (value & ~bitToTurnOff);
}
```

The following method flips a bit to its opposite value:

```
public static int FlipBit(int value, int bitToFlip)
{
return (value ^ bitToFlip);
}
```
