Bubble sort values Programme c++ using nested for loop

int main()

{

int arr[50],n;

cout<<"how many number"<<endl;

cin>>n;

for(int i=0; i<n; i++)

{

cout<<"enter the number"<<i+1<<":";

cin>>arr[i];

}

cout<<"THe orignal numbers are"<<endl;

for(int j=0; j<n; j++)

{

cout<<arr[j]<<endl;

}

int hold;

cout<<"Now the sorted vales are"<<endl;

for(int i=0; i<n; i++)

{

for(int j=0; j<n-1; j++)

{

if(arr[j]>arr[j+1])

{

hold=arr[j];

arr[j]=arr[j+1];

arr[j+1]=hold;

}// if end

}//nested for end

}//for end

cout<<"The sorted vales are"<<endl;

for(int i=0; i<n; i++)

{

cout<<arr[i]<<endl;
