confused with sorting struct

[kurz7]

hi guys, anyone see what is wrong with this, i can implement this without structs but using structs i can not do it.

thanks!

void swap( student_t *fval, student_t *sval )
{
	student_t temp;
	temp = *fval;
	*fval = *sval;
	*sval = temp;
}

What are you trying to swap? Your swapping as listed here only swaps the value. As such, the ID doesn't get changed, the ID just gets a different value assigned to it. Is this really what you want? Or are you trying to swap the whole structure / contents?

sorry i didnt make the problem clear, all i wanted to do was sort the structure from lowest mark to highest mark with student id respectively

hi ive fixed up my code but i cant seem to swap the elements in the array. anyone can help?

in my swap function how do i make it so i can swap the structure in the array? for example if element 1 is bigger then element 2 in the array, i want to swap the elements around. so element 2 jumps into slot 1 and element 1 goes in slot 2...

THANKS!
