/********************
OUT PUT*****************

 Enter the value of a&b 11 12

 Value of a&b in x1:11 12

 New Value of a&b in x1:12 13

 Enter the value of a&b 10 14

 Value of a&b in x2:10 14

 New value of a&b in x2:9 13


******************** OUT PUT*****************/

Output :-

 Enter the value of a&b 11 12

 Value of a&b in x1:11 12

 New Value of a&b in x1:12 13

 Enter the value of a&b 10 14

 Value of a&b in x2:10 14

 New value of a&b in x2:9 13
