How to get the bit after shifted?

[howa]

e.g.


int i = 5; // i.e. 0000...101

// shift i to the right

int j = i >> 1; // how to get the `one` being shifted?

thanks.

e.g.


int i = 5; // i.e. 0000...101

// shift i to the right

int j = i >> 1; // how to get the `one` being shifted?

I think you are asking how to save the LSB of i. If so, the answer is
to use logical-and, but it must be done before the shift:

int k = i & 1; // Save a copy of the LSB
int j = i >> 1; // Now the LSB is gone

int j = i >> 1; // how to get the `one` being shifted?

int k = (i & 1);

I believe you mean bitwise-and?

So I did. I used the right one in the code, but spelled it wrong in the
text.
