Am i doing something wrong?

[easy]

im just doing a little exercise on the bubble sort algorithim, i included two ways of incresing its speed.
1. Breaking out of the loop if no swaps are made
2. Decreasing the inner loops lenght each pass
I think there is two ways of doing it. This way i think is better coding practise but it takes alot longer to compile. is it confusing the compiler a bit?

const int SIZE = 10;//size of array
const int UPPER = 10;//highest value

int main()
{    
    int array[ SIZE ];
    int temp;
    
    srand( time( 0 ) );
    
    for ( int counter = 0; counter <= SIZE; counter++ )
    {
        array[ counter ] = rand() % UPPER;
    }//end for
    
    for ( int pass = 0; pass < SIZE ; pass++ )
    {
        int swap = 0;
        for ( int counter = 0; counter < ( SIZE - pass ); counter++ )
        {
            
            if ( array[ counter ] > array[ counter + 1 ] )
            {                
                temp = array[ counter ];
                array[ counter ] = array[ counter + 1 ];
                array[ counter + 1 ] = temp; 
                swap++;
            }//end if
        }//end inner for
        if ( swap == 0 )// no swaps made
        {
            break;
        }
    }//end outer for
    
    for ( int counter = 0; counter <= SIZE; counter++ )
    {
        cout<< array[ counter ]<< "\n";
    }//end for                
    return 0;
}

the other way i had it was

for ( int pass = 0; pass < SIZE ; pass++ )
    {
        int swap = 0;
        int i = 0;
        for ( int counter = 0; counter < ( SIZE - i ); counter++ )
        {
            
            if ( array[ counter ] > array[ counter + 1 ] )
            {                
                temp = array[ counter ];
                array[ counter ] = array[ counter + 1 ];
                array[ counter + 1 ] = temp; 
                swap++;
            }//end if
        }//end inner for
        i++;
        if ( swap == 0 )// no swaps made
        {
            break;
        }
    }//end outer for

which way is better

confusing the compiler? reducing cases will always simplify runtime.

You have a problem understanding loops and arrays. You have

const int SIZE = 10;//size of array
...
    int array[ SIZE ];

Then your loop is defined as

for ( int counter = 0; counter <= SIZE; counter++ )

Array size is 10, you load 11 values and blow past your array. You have to make sure you never reference array or beyond.

As for your question, the first one. In the second code, all i represents is pass so it's a waste of space.

.

is this better?

for ( int counter = 0; counter < SIZE; counter++ )

im noob so i always have to think about whether to put < or <=

my mistake ty

Yes. Now you have more loops. Check them, too.
