The increment operator.

But you can only use it on variables, not constants.

++5 is incorrect.

Actually your code will give error in 2nd line where u wrote ++5 . Here lvalue or expression not assignable error will occur. You should write++x instead of ++5 First int x=3; In next line u used pre increment int x=++x; Here x will be increase by 1 . And it will assign to variable y and the present value of x will be 4. In next step int z=y+x Here z=4+4= which will give 8 as a output . Hope you understood.

++5 not do anything, but ++x do. ++ is an increment operator. ++x (pre increment) is same as x=x+1 x++ (post increment) same as x=x+1; Difference is pre increment, first increments it's value then uses. Post increment first uses value then increments.. For more, read about incrementstion operators.

++ means increament by 1 and -- means decrement by 1
