Explanation In the above program two fo r loops are used. The inner fo r loop generates four binary

bits for each hexadecimal number and assigns it to array b in [ ] [ ]. The 0 to F hexadecimal numbers

are taken from the outer fo r loop. If the bit is 1 counter % c ' is increased. The value of c is checked for

even or odd condition. If c is odd the parity b it% 0' is displayed otherwise ' 1' .The output is displayed.
