Something in the site's tutorial i can't understand in the array part.

in the array lesson in the site's tutorial this code is goven and im not convinced with it because the 'i' is incremented before its use since the ++ comes before it.and as i know that this wont excute the first element in the string array.am i right?

Code:

---

char astring[10];
int i = 0;
/* Using scanf isn't really the best way to do this; we'll talk about that
  in the next tutorial, on strings */
scanf( "%s", astring );
for ( i = 0; i < 10; ++i )
{
    if ( astring[i] == 'a' )
    {
        printf( "You entered an a!\n" );
    }
}

---

no ^.^ i dont think so...

explanation?

the compiler builds the for loop like this:

Code:

---

/*/for ( i = 0; i < 10; ++i )
{
    if ( astring[i] == 'a' )
    {
        printf( "You entered an a!\n" );
    }
}/*/

i = 0
while (i < 10)
{
    if ( astring[i] == 'a' )
    {
        printf( "You entered an a!\n" );
    }
    ++i;
}

---

It's a for loop, i is incrimented at the end of each pass thru the loop, in this case it dosen't matter weather you use i++ or ++i.
If you were doing something like this

Code:

---

a=++i;

---

Then i would be incrimented before being assigned to a.
