Question

What will be the value of y if x=5 y= ++x + --x + ++x ​

Answer 1

Answer:

c++ or g++ compiler. It will give output as y=12.

Expression include pre and post increment operator.

x++ will be 5 (if value of x is 5) only as it prints or holds the value first than increment the value later. It is a case of pre-increment operator

++x will be 6 (if value of x is 5) as it increments the value first than prints or holds the value later. It is a case of post-increment operator
