Thread: A question about the place of "printf" with "while" and "{}"

Hi,
I am a beginner of C who is currently using The C Programming Language to self-study.
However I am confused by one little problem:
When I put

Code:

printf

inside the

Code:

while{}

, it gives the output of every single loop,

However, since I want only the final answer and thus try to put the printf out of {}, which is after while, nothing shows then.

This one with nothing shown is copied directly from the book so I really wonder what's wrong, and how exactly should I modify it to make it output the total number of lines?


Thank you!

You should post your code (using code tags) and output here directly, rather than posting screen shots.

In the second example, you need to trigger EOF to end the loop. This is done by entering Ctrl-Z (on Windows) or Ctrl-D (on Unix).

Thank you, Ctrl-D works.
And sorry, I see Next time I will post the code directly.
