Correct output but still isnt getting submitted

#1

My code is giving the correct output for all the testcases but it still shows error in two testcases while submitting. Does the method needs to be the exact for it to get submitted?
#include
using namespace std;
int main() {
int n=0;
cin>>n;
int arr[n]={0};
for(int i=0;i<n;i++){
cin>>arr[i];
}
int target=0,x=0;
cin>>target;
for(int i=0;i<n;i++){
x=arr[i];
for(int j=i;j<n;j++){
if(n==1){
cout<<arr[i]<<" and “<<arr[i]<<endl;
}
if(arr[j]==target-x){
cout<<arr[i]<<” and "<<arr[j]<<endl;
break;
}
}
}
return 0;
}

#2

for input
5
1
3
4
2
5
4
correct output
1 3

your Output
1 and 3
2 and 2

because 2 comes only once in the array

#3

i edited the code and nowit is showing the correct output but still cannot submit it

#4

in question it is mention that
Print each pair in increasing order.

so first you have to sort the array
