Changing your readf format specifier to include the new line should work.

Thank you!
Adding the \n seems to solve my problem: ```readf("%s\n", &f1.num)```
I have two further questions about this!
a- What is the difference with this syntax with the exclamation mark?
```readf!"%s\n"(f1.num);```
That is a template.
It'll type check that the format specifier matches your arguments.

b- Do I need to put ```/n``` in every readf statement? I mean,
considering that every input gets entered after pressing intro key (and
I guess this is what introduce the \n)
Yes.
