Bitwise operator uses &

Ex- 1 & 3 = 0000 0001 & 00000011 = 0000 0001 

Short circuiting technique is used by logical operators by not evaluating the values of its arguments and hence sometimes called short circuit operators .

Ex- let i = 0,

Then , ( i && j) = 0 

This time only value of i is evaluated  which is 0 and answer is concluded without calculating value of j because whatever be the value, the answer will always be 0. 

So , in this way logical operators short circuit by not even considering what might j be, the final value of the complete expression will always be 0 .
