Sorting in arrays

Question

using namespace std;

int main() {
int n;
cin>>n;
int arr[n];
for(int i=0;i<n;i++){
cin>>arr[i];
}
for(int i=0;i<n-1;i++){
for(int j=0;j<n;j++){
if(arr[j]<arr[i]){
int temp=arr[i];
arr[j]=arr[i];
arr[i]=temp;
}
}
}
for(int i=0;i<n;i++){
cout<<arr[i]<<" ";
}
cout<<endl;
return 0;
}

Answer 1

I corrected the second for loop and swap statements,

for(int i=0;i<n-1;i++){
for(int j=i+1;j<n;j++){
if(arr[j]<arr[i]){
int temp=arr[i];
arr[i]=arr[j];
arr[j]=temp;
}

Answer 2

It's not working properly
