Thread: bubble sort with an array

i need to sort the array of int id[10]. this is how is see it in the book but it does do anything. it compiles with no problem but doesnt change any order. any help i would greatly apreciate it. thank you.

Code:

void CD::bubblesort(int id[10],int last)
{
for(int current=0;current<last;current++)
bubbleup(id,current,last);
return;
}

void CD::bubbleup(int id[10],int current, int last)
{
	for(int walker=last;walker>current;walker--)
		if(id[walker]<id[walker-1])
		{
			int temp=id[walker];
			id[walker]=id[walker-1];
			id[walker-1]=temp;
		}
		return;
}

actually now i tried with a breakpoint and ran it without debugging and it seems like it doesn't even run through the sort because it doesnt stop there.heres how i call it in a switch. thanks for looking at it.

Code:

case 2:  
	{	ifstream infile;
	infile.open("file2.txt");
	getCD(infile);
	infile.close();
	bubblesort(id,last);
	
	}
break;
