Okay, here we go.

Life interfered, AGAIN, with my programming.

This is the basic program, now I'm looking at the problems with printing the histogram vertically.

More planning, obviously....

Oh, dear.

I used more than two lines. I used more than two lines for the INTRODUCTION.

I re-wrote it this morning, with no functions.

Now it runs, but when you enter an EOF, it prints...

Okay. :)

You know this stuff awfully well. You sound like you've been through it more than once. I don't remember textbooks I blew through ten years ago, let alone when K&R was written.

You...

Okay, I've been working on 1-13.

Once I broke it down into tasks, perhaps it isn't that difficult.

I have, perhaps, broken it down further than I needed to, but doing so helped me wrap my mind...

Exercise 1-13, make a histogram. I would list my problems, but ohmygod...

I started thinking about what you said, and I realized that it doesn't matter.

The goal is to replace strings of blanks with single blanks, and then I realized I was over-thinking it, and making...

Thank you, Franklin.

I took your suggestion of a flag, and after wrestling with it for a few hours, came up with this:

/*
* copy.c
*
* Exercise 1-9. Write a program to copy it's input...

Oh, for goodness sake.

I see it.

{sigh...}

So, it's not comparing anything in my code, it's assigning the values of space, tab and newline to the variable x, which is always successful, and,...

Oh! The return character! Of course! duh...

Now, of course, I have another problem. I thought 1-8 would be easy, but not so much.

The code:

/*
* blank.c
*
* Exercise 1-8, write a...

Okay, I'm back. :)

I've been examining if.

For 1-6, I wrote this, thinking that perhaps I was just making it too complicated:

/*
* verify.c
*
* Exercise 1-6, Verify that the...

Thanks to both of you.

I see the problem with the while loops.

I'll try the control-D combination, then I'll gnash my teeth and pull my hair for awhile on another way to test input.

Hello, ladies, gentlemen.

First I suppose I should introduce myself.

I've been poking at C since a long time ago, somewhere around 1990. (Don't misinterpret that. "Poking at C", in this...
