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, therefore, always true. So every if loop executes on every character.
/*******************************/
Update.
I re-wrote the code, and made another rookie mistake that plagued me for two hours.
This code is the solution:
However, in the comparisons, I initially used double quotes, and the program insisted that there were zero spaces, zero tabs, and zero newlines-- exactly what I'd initialized the variables to. They weren't incrementing.
I finally found the answer in K&R-- they had mentioned it, and I read right over it. It has to be single quotes, double quotes is a text string.
I won't say that an exercise looks easy again. I'm off to look at 1-9.

Okay, I'm back.
Now I'm completely baffled.
Exercise 1-9, with this code:
When I run this code with a text file, using cat /Text.txt|./a.out
the only thing that happens is that another curser appears and says:
Bus error.
My other programs still run, this is the only one that creates a bus error.
---------- Post updated at 05:02 ---------- Previous update was at 01:37 ----------
Okay, I replaced the final printf with a putchar, and the bus error went away.
The program now runs, but it doesn't do anything like it should.
Now it deletes "random" characters, (I'm sure there's a pattern, or at least a reason, but I don't see it.) and leaves long lines of blank spaces. The mystery continues.

I took your suggestion of a flag, and after wrestling with it for a few hours, came up with this:
It works, and it works reliably, but there's one thing I don't like about it.
If I'm following it correctly, (and I'm pretty sure I am) the flag blank carries a 1 as soon as a single blank is encountered.
That is, if you ran it on this sentence, the space between "That" and "is" would set blank to one, and it would be one until it was re-set, and it wouldn't be re-set until the word "if".
So it would work, it wold do its assigned task correctly, and the code would use the first else if when it didn't have a blank set, and the second else if when it did.
So my only gripe is that the flag blank isn't reliable-- it does not show the truth about whether the first blank has been encountered at all times.
On the other hand, when I swore at it, I woke my wife up, so I think I'll put it away for tonight.

I want to insert "Text" in each file as a place where I mentioned below "Insert Text Here". These files are something like news of newspaper. Generally, newspaper headlines contain one or two lines.
I don't know how it can be identified whether Text is inserted after first line or second line.
