    Talking final exam in the morning

    Code:
    #include <iostream>
    
    using namespace std;
    
    int main()
    {
    	const int SIZE = 5;
    	int values[SIZE], counter, temp;
    	bool swap;
    
    	
    	for (counter=0; counter<SIZE; counter++)
    	{
    		cout<<"please input a number"<<endl;
    		cin>>values[counter];
    	}
    
    	do
    	{	swap = false;
    		for (counter=0; counter<values[counter-1]; counter++)
    		{
    			if (values[counter+1]>values[counter])
    			{
    				temp=values[counter];
    				values[counter+1]=values[counter];
    				values[counter]=temp;
    				swap=true;
    			}
    		}
    		while(swap);
    	}

    So has the formating of your coded helped any? - assuming Salem formated it for you.

    Maybe there is no new code. He just wanted to remind us that it doesn't work.

    Anyway, I'm going to bed. My last advice: Check the part on do-while() loops

    In which case ammanbesaw has not been reading anything we're written. And in which case ammanbesaw can figure out the problems without our help.

    Your code is not indented correctly. Salem fixed it for you in your first post, so if you go back and read that, then you might find the answer to why it isn't working correctly.

    He didn't make it work, he just made it so that you can see more easily where the problem is.

    Look closer at your outer do-while loop... its quite easy to spot the mistake

    Do you see anything wrong in statement

    for (counter=0; counter<values[counter-1]; counter++)


    ?????

    He's also going to get a crash because he's trying t o check an out-of-bounds array member. When counter = 0, he's trying to check

    counter=0; counter<values[counter-1];

    which is values[-1] !!!

    Probably not a crash, but nevertheless not a good thing.

    Change
    Code:
    		}
    		while(swap);
    	}
    to
    Code:
    		}
    	
    	} while(swap);
    The while statement should be after the closing bracket from do.



    And I did get a crash in the middle of execution most likely because of what you guys just said (about out o' bounds array member)
