Answer / suman halder
++a is an unary expression which signifies pre-increment operation...so ,pre-increment will be evaluated before the binary operation takes place..
b=++a + ++a;
here,a will be incremented twice and then binary operation is performed...
so,
b=12+12 which produces 24...

in first increment the a will become 11. And the second
increment the a will become 12. b=++a + ++a ; have same
variable so b=12+12=24
