How to use the ++ line in both prefix and postfix method?

Question

"int x=3;
int y=x++;"

and

"int x=3;
int y=++x;"

What are the difference in the value of x?

Answer 1

The first version says set y equal to x and then add 1 to x, so here y is 3 and x is 4.

The second version says add 1 to x and then set y equal to x, so here x is 4 and y is 4.

In both cases x is the same, you are starting at 3 and adding 1 to it, the difference is the value held in y.
