Why my bubble sort is code is not work on sololearn compiler?

Question

This is the code---

//Program to sort an array using Bubble Sort
#include <iostream>
using namespace std;
int main()
{
int a[50],i,n,item;
int temp,loc;
cout<<"Enter the size = "<<endl;
cin>>n;
for(i=1;i<=n;i++)
{
cout<<"a["<<i<<"]= ";
cin>>a[i];
}
for(int k=1;k<=n;k++)
{
for(i=1;i<=n-1;i++)
{
if(a[i]>a[i+1])
{
temp=a[i];
a[i]=a[i+1];
a[i+1]=temp;
}
}
}
cout<<"----------------------------------"<<endl;
cout<<"sorted list is :"<<endl;
for(i=1;i<=n;i++)
{
cout<<"a["<<i<<"]="<<a[i]<<endl;
}
return 0;
}

Answer 1

because it has two cin >> .
sololearn doesn't support to enter an input each time the code
reaches it .
instead you have to enter the values separated by spaces in one go.
disappointing .

Answer 2

oh thanks
