Bubblesort error

[Penx]

I have some homework where I have to use Bubblesort to arrange 500 randomly generated numbers. (In code only 10 until it works). But on line 55 I am getting an error that says:

no match for 'operator<<'in 'std::cout << Bubblesort[[[int*][&array]], n]'

Any help on this error would be much appreciated :D

why you use reserved words as variable names?

[Raman009]

You are getting an error because "operator <<" does not know how to handle Bubblesort().
Remove " cout << " in front of BubbleSort.
You can either print the elements in the BubbleSort function itself. or
in the main function using loop .

for(int i=0 ; i<sizeOfArray ; i++){
std::cout << array[i] << " " ;
}

[iantac]

cout << "The Array after being Bubblesorted is: " << endl;
Bubblesort(arr, n);
for (int k = 0; k < 10; k++)
{                                                                            
     cout << arr[k] << " ";                                                 
}

I changed int array[10] to int arr[10]
I used that and the program worked.. but it's not sorting
what's the value of n when the Bubblesort function is about to be called..
There's no value at n

[ne555]

¿which `reserved words' are you referring to?

@OP: void Bubblesort(int array[], int n); ¿how do you expect to print void?

@ Raman009
Thanks, I tried to print the result within the Bubblesort function only to get "44x0303" to display. So I made it print in a for loop and it worked fine.

@iantac
Just the way I have been taught, I normally declare all the variables I use then get rid of redundant code at the end.
And I was running into the same problem of it not sorting, but my problem was when I learned Bubblesort today I brain farted and saw the "1" as an "L". So I changed all the l's to 1's and set int n=10; and I got it to work.

Thanks for all the help! Here is the finished product.

You should take a look at comb sort, lots of fun to be had with comb sort.
