Variables values question

Question

#include <iostream>
using namespace std;

int main()
{
int a, b;
int sum;
cout << "Enter a number \n";
cin >> a;
cout << "Enter another number \n";
cin >> b;
sum = a + b;
cout << "Sum is: " << sum << endl;

return 0;
}

The above code is supposed to let me input two values I.e for the variables a and b before it sums it but when I tried it, it just gives the opportunity to enter one value and gives me a sum immediately.

Please why is this

In SoloLearn you need to enter all the values at once, one on each line.
