thanks sagar! so just to confirm ,what i get from above is that the x value before the first addition is first updated from 3 to 5( due to 2 pre increments) and then 5 and 5 is added to make the 10.This is then added to 6( as before the second addition x is updated again)
if y = x++ + ++x + x++ then will the value seem like for the first addition(x++ + ++x ) as 4+4?(since the single pre increment increases the value of x by 1) ,and then for the next addition it would be 8+4(since post increment here so x doesnt change)?finally the value of x is 6? pls correct me if wrong ...
