Answers:

Ans: Lvalue required..

it will print first value .but in second value it will perform preincrement operater which will result as a int value but we can't postincrement that value,we can postincrement variable.so it requires a variable to store that value so it gives Lvalue required error.

This snippet will print x=11,y=10 because the arguments passed to a function are calculated first and the order is from right to left. So value of x and y is 11 and 10
