Here this should make it easier for you...

Problem_________|___Solution__|

int x=20, y=35; (here the values of x,y are apparent.)

x = y++ + x++; (x=y+x+1) or(x = 35 + 20 + 1)x = 56
But; you incremented y, its now = 36

y = ++y + ++x; (y =(y+1)+(x+1)) or(y=1+36+1+56)y = 94
This is the second time you incremented
x so it is now = 57.


The reason that you are getting different increases
for x and y is that when you use statement(x=x++) you are
first stating that x is = to x, and then 'increment x.
when you use statemnt(x=++x) you are first
stating 'increment x, then that x is = to x.

look at the code and description in the chart below.

table:
code = meaning;
int x=2
int y=2
-------------------|
(x=x++) = "x = x, x + 1" (increment happens after)
(x=++x) = "x = (x+1)" (increment happens before)
(x=y++) = "x = y, y + 1" (increment happens after)
(x=++y) = "x = (y+1)" (increment happens before)

if you want to add y to x and then increment y use this
statement:

x+=y++

if you want to increment y and then add it to x use this
statement:

x+=++y

#define MAX(x,y) (x) >(y)?(x):(y) main() { inti=10,j=5,k=0; k= MAX(i++,++j); printf("%d..%d..%d",i,j,k); }
