RE: [Dev-C++] Basic C question: scanf

[Mary S. <ms...@in...>]

Thanks to everyone who replied. I had expected the <cr> to be a legal input.
Thanks for the info.

No, it doesn't hang.
After the printf in the loop is executed, scanf still waiting legal input.

  while (scanf("%lf", &salary) == 1) {
     ...
  }

So to finish scanf, you have to give illegal input or non numeric
character, like 'x' (or another alphabet character you like) then press
[Enter].

Try to give input like this:

Enter salaries: 100 200 150 600 x [Enter]



If you write loop like this

  while (scanf("%lf", &salary) != EOF) {
     ...
  }

You can use <ctrl>Z to finish input.
