Answer / shashi shekhar

In this type of question the operation done from right side of the expression.Here we can see two types of increments pre and post increment,in post first the value assigned then increment but in pre first the value is incressed then the value assigned.

"1" then the this expression gives the output "4".

What will be the output of x++ + ++x?..

Answer / prem

if x=3
y=x++ + ++x;
y will be 8
x will be 5

calculating y part
1) x++ is 3 and x will be 4
2)++x is 5 bcz x is incremented then assigned so x=5

so y finally gives 8.
