for loop increment condition ?

[kenneth6]

class* object;

int num=7-object->getNum();
for(int i=0; i<num; i++)
{ ...... }

for(int i=0; i<7-object->getNum(); i++) 
[U]OR[/U] 
for(int i=0; i<(7-object->getNum()); i++)
{ ...... }

Are there any difference from the above two sets of codes?

I cannot get the expected output from the second set. what is the reason for that?

Are you decrementing number that is returned with getNum()?
If so there is the difference,if not those for statements are equal.

what do you mean by "decrementi ng number"?? the num returned from function is constant for each time.

Then it should give you the same output.Can we see what are you doing in for loops?
