Can't figure out my mistake

#1

I saw the hint video also, but can’t seem to figure out where I am going wrong.
Following is my code:

#include
#include
using namespace std;

int main()
{
int n;
cin>>n;
int arr[1000];
for (int i=0;i<n;i++)
{
cin>>arr[i];
}
int num;
cin>>num;
sort(arr,arr+n);
int i=0;
int j=n-1;
while(j>i)
{
int sum = arr[i] + arr[j];
if (sum == num)
{
cout<<arr[i]<<" and "<<arr[j]<<endl;
}
else if (sum>num)
{
j = j-1;
}
else if (sum < num)
{
i = i+1;
}
}
return 0;
}
