How increment and decrement opertors works in c

[shivapadma]

i want clear explanation of increment and decrement operators in c.

can any body help in solving the following expression
a=10
c=++a + ++a
when i am executing this code ,the answer is c=24
how it is possible?

well ++ hs higher precedence thn + and therefore ur expression becomes
(++a) + (++a)
and the result is 23 ;

(11)+(12)

The result will be undefined. You shouldn't depend on that type of expressions because it could be anything.
