what is the difference between i++ & ++i

First case

int i = 10;
int j = i++;

After execution value of i would be 11 and value of j would be 10.
As this operator is POSTincrement , increament will be done AFTER the assignement.


Second case

int i = 10;
int j = ++i;

After execution value of i would be 11 and value of j would be 11.
As this operator is PREincrement , increament will be done BEFORE the assignement.

hi

once lookat this

string[] items = {"a","b","c","d"};
int i = 0;
foreach (string item in items)
{
    Console.WriteLine(++i);
}
Console.WriteLine("");

i = 0;
foreach (string item in items)
{
    Console.WriteLine(i++);
}

output will be

1
2
3
4

0
1
2
3

i hope it helps you...

Thanks&&Regards
