Increment decrement operators

[Rohan Pujari]

int the line

int i =x++ + ++x ; i = 4

because according to operator precedence ++x evaluates to 2 and then x++ again to 2 thus giving output i=4 and x = 3

but

int i = x++ + x++ the output is x=3 i=3
could some one explain me how it got evaluated to the above output.

[Atul Prabhu]

i = x++ + x++;

i = 1 + 2 = 3 and x = 3.

Before evaluating the second x++ the value of x is 2, hence it takes the value 2 and not 1.

i = 1 + (2++)
