Running code that takes input.

Question

Why does SoloLearn code take input before even running? Is this a limitation or by design? And why?

Answer 1

Yes, because it compiles all non-web code at server side, so it need entering all input before sending code back to server.

It is a limitation

Answer 2

//Code takes input ,if write inputs code , that's not a problem of sololearn 🤷

Answer 3

Sorry, let me clarify. Let's say I write:

cout << "Input a number";
cin >> num;

SoloLearn prompts that the program needs an input before running. I dont even get to the output yet. This is inconvenient for the user, because half the time they don't know what to input...

Answer 4

Thank you. This makes the SoloLearn app lightweight I assume, because it doesn't need to download the necessary compilers for each language, yes?

Answer 5

Yes only web code are compiled locally.

That's also why some new JavaScript syntax doesn't work on users with older version browsers
