$($counting $N$ from the least significant bit, starting from $0),$ and for determining if all bits are on in a range of positions.

You must add those macros $(1\mathrm{.}0\%)$

A couple of sample runs are $...$

$>$ Bit$0$ps

Enter an integer : $31$

$31$ is odd

Enter an integer and a bit number : $313$

$31$ has bit $3$ on

Enter an integer, start and end bit numbers : $3124$

$31$ has all those bits onEnter an integer : $30$

$30$ is even

Enter an integer and a bit number : $306$

$30$ has bit $6$ off

Enter an integer, start and end bit numbers : $3046$

$30$ has not all those bits on
