++operator

[Crirus]

There is any difference between

for (int line = 0; line < linesPerPage; ++line) {
}

and

for (int line = 0; line < linesPerPage; line++) {

}

?

Cirius,

Both of the followup posts to your question are correct. I just wanted to
clarify how the itterator in the for loop works out. The for loop consists
of four parts: 1. the initializer (int line = 0), the termation condition
(line < linesPerPage), the itterator (line++ or line++), and the statement
(everything within {}). In the scenario you presented there will be no
difference since the initalization and termination conditions are not
affected by the itteration statement. The itteration statement (++line) is
executed after the statement portion (everything within {}) of the for loop
is executed...since the iteration statement is not a compond statement
(i.e. it is on a line by itself) you'll se no difference between ++line and
line++.

| Hi Cirius.
|
| in addition to what Rob said:
|
| in this specific case there are no differences, you could have difference
in
| a case like:
| int i = 0;
| ...
| int n = i++;
| // now n = 0, i = 1
| OR
| int i = 0;
| ...
| int n = ++i;
| // and now n = i = 1
