About x++, x+

Question

can someone plz tell me what's the difference between x+ and x++?

Answer 1

9 :) I guess

Answer 2

when u encounter ++x, first increase x value with 1 then do any operations on that statement . hence called pre increment.

when u encounter x++, first perform operations on that statement for x without bothering about increment but after that statement x value will be increment by 1. hence post increment

example: x=5;
y=++x + x++;
y will be 12 as y=6 + 6
but after this statement x becomes 7

now answer this
int x=6;
int y=++x - x++ + ++x;
cout<<y;
cout<<x;

Answer 3

y=7-7+8
so y= 8

and thrice increment on x makes it 9
