Code is giving Error. Question is to find the pair in array whose sum is equal to num

#1

Code :-
#include<bits/stdc++.h>
using namespace std;
void targetSum(int arr, int n, int target)
{
int left = 0;
int right = n - 1;
while (left <= right)
{
int sum = arr[left] + arr[right];
if (sum > target)
{
right++;
}
else if (sum < target)
{
left–;
}
else
{
cout >> arr[left] << " and " << arr[right] << endl;
left–;
right++;
}
}
}
int main() {
int n;
cin>>n;
int arr[n];
for(int i=0;i<=n;i++){
cin>>arr[i];
}
int x;
cin>>x;
targetSum(arr,n,n);
return 0;
}
