++x is pre-increment

say for example
the value of a=1
int a,r;
r= ++a;

now the value of "a" is incremented to 2 n then assigned to r...


x++ is post increment
say for exmaple

the value of a is 3

int a,r;
r=a++;

the value of a(initially 3) will be assigned to r..... n
then the value of "a" gets incremented to 4.
