Answer 1

U haven't specified the return type for main()
that is, write int main() and then return 0 at the end.

Answer 2

The gets() function has a security vulnerability( buffer overflow), so it is preferable to use fgets() instead because it requires a second parameter which is the size of the buffer you wanted to store data in it.
Additionally, you should remove the = sign between fputs and the parentheses '()'.
Finally you need to specify the return type of your main function.

Still not work
error: too few arguments to function 'fgets'

Answer 4

You need to enter 12 lines like:
Name0
Pass0
Name1
Pass1
Name2
Pass2
And so on. That is because sololearn doesn't use an interactive IDE.
If you are using fgets, you need to specify the size of the buffer.
