1>On the 1st que the ans. is 12
bcz perform the pre increment 1st then add them.
After the pre increment the value of i becomes 6 and
then it perform the add operation i.e. i+i=6+6=12.
2>output is 10
It 1st perform the pre operation but there is no pre
operation in the que.
2ndly it perform the operation i.e i+i=5+5=10.
3rdly it perform post operation i.e i++ so i becomes 6.
but here the output is 10.
