Thread: aMethod

What does the function below do?

Code:

int aMethod ( nodePtr list, int (*compar)(void *, void *) ) {
int b = 1;
nodePtr o1 = NULL, o2 = NULL;
for ( ; list ; list = list->next ) {
o1 = list;
if ( o2 != NULL && compar(o1->data,o2->data) > 0 ) {
b = 0;
break;
}
o2 = o1;
}
return b;
}

it checks to see if the list is stored in descending order.

Run it and find out.
Oh and while you're at it, learn how to post formatted code. Code which is all indented to the left hand side is terribly hard to read.

No it doesn't.

really?

read the code again.

I did, you're making way too many assumptions about the nature of the function which compar points to.

It might be an order, but it could also be an increasing order.

Or maybe all odd numbers before all even numbers.

For all anyone knows, the function could be returning rand()
