Buble sort with pointers

[msrt92]

How can i use pointers to pass the array to sort function?

#include<iostream.h>
void sort (int arr[]);
void main ()
{
	int arr[5];
	cout<<"Enter Numbers To Store In Array"<<endl;
	for(int i=0; i<5; i++)
	{
		cin>>arr[i];
	}
	
	cout<<"Beofre Sorting"<<endl;
	for(i=0; i<5; i++)
	{
		cout<<arr[i]<<",";
	}

	//sorting array 
	sort(arr);
	
	cout<<"After Sorting"<<endl;
	for(i=0; i<5; i++)
	{
		cout<<arr[i]<<",";
	}

}


void sort (int arr[])
{
	for(int i=0; i<4; i++)
		{
			for(int j=0; j<4; j++)
			{
				if(arr[j]>arr[j+1])
				{
					arr[j]=arr[j]+arr[j+1];
					arr[j+1]=arr[j]-arr[j+1];
					arr[j]=arr[j]-arr[j+1];
				}
			}
		}
}

You... already using them.
Line 19: array type decays to pointer here.
Line 30: (int arr[]) is equvalent to (int* arr)
