[Dev-C++] Pos and Pre Incremental/Decremental Operators Examples

[<and...@su...>]

Dear Users:

Please consider the following examples:

Example 1:
...
int c;
c=0;
cout << c++; ---> it will print 0;
cout << c;   ---> it will print 1;
c=0;
cout << ++c; ---> it will print 1;
cout << c;   ---> it will print 1;
...

Example 2:
...
1-int i;
2-for(i=0; i<10; i++) cout << i; ---> it will print 0 to 9
3-for(i=0; i<10; ++i) cout << i; ---> it will print 0 to 9 (too!)

Statements/Questions:
1-I only have example #1 style to teach pos and pre incremental operators;
2-I thought in Example 2, line 3 an output like numbers 1 to 10. Why this
not happens?
3-Does anybody have good and simple examples of using pos and pre
incremental/decremental
  operators?

Andre
