Multiple Times Input?

Question

How to input multiple times in sololearn?
Like:
[...]
string text1 = Console.ReadLine();
string text2 = Console.ReadLine();
Console.WriteLine("Input1: "+text1);
Console.WriteLine("Input2: "+text2);
[...]
But it only prompts for input once...And Input2 is empty.

Or :
Simple Calculator:
[...]
for(;;)
{
Input number = Console.Read();
//Calculation
//Result
//Repeat
}
[...]

Any solution ?
