why doesn't the program ask for input twice ?

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;
}
it just ask the users once
and if you enter just one number you will run into an error

Answer 1

Please check your code again.
It's asking for input..
Sometimes this happens when network connection is slow..
It also shows no output once network issue occurs.

Answer to edited question:

It will not ask for twice input.
You have to use new lines in that for multiple input
