Tell me if i'm right, i want to make sure i understand that.

Question

if x=9;
y=x++;
the answer is:
x=10;
y= 9;

but if
x=9;
y=++x;
the answer is:
x=10;
y=10;

It's ok? anything else about that i should know?

Answer 1

Hi Maor

When is executed y=++x, this is prefix operation. First x is incremented plus one and then x value is assigned to y.

When is executed y=x++, this is posfix operation. First the x value is assigned to y and then x is incrementes plus one.

I hope it helps.
