  • Q2. How would++(++i) work
  • Ans. 

    The expression would increment the value of i twice before using it in the operation.

    • The value of i would be incremented by 2 before being used in the operation.

    • This is equivalent to writing i = i + 2; followed by the operation using the new value of i.

    • For example, if i was initially 3, the expression would evaluate to 6.
