How to find and deal with maximum and minimum numbers?

[zj262144]

Hi, I'm a C beginner.
I want to write a C.
The pseudocodes are like this:

User enters some numbers (use -1 to end)
The compiler find and delete the maximum and minimum numbers
Then average remained numbers
Finally print the result

Thanks in advance!!!

Do your own homework.

Homework is there to TEACH you, if you do not do it yourself
you will NOT learn anything

Doesn't look like pseudocode to me, mor like a (homework) task. Maybe the
following helps to get you started:

read number
counter=1
max = min = sum = number

loop
read number
counter++
if number max
max = number
else if number < min
min = number
sum += number
repeat while number not -1

sum -= (min+max)
counter -=2 /* to account for min amd max not being in anymore */
result = sum/counter
print result

Sorry, but I don't think that answers the OP's question. He wants the
*compiler* to find and delete the maximum and minimum numbers.

Tricky - but I suppose the obvious approach is to write a code generator
containing a hard-coded list of the answers protected by preprocessor
definitions (or, if that's not allowed, use if(0) and then switch on as
many optimisations as you can find), and then shell out to the compiler.

I believe this to be wrong wording on the OP's part.

It's achieveable in C++ since templates provide a Turing-complete
meta-language. However C doesn't.
To the OP, c++ is the next newgroup.

NO
THIS ISN'T HOMEWORK!
The homework just asks us to estimate the maximum from 10 integers.

However: what you wrote isn't even an attempt to program something in C. Try
it, if you get stuck post what code you have and there will be people
helping you.

This has nothing to do with the C language. First work out the
algorithm (which is fairly simple). Then write the C code to
implement the algorithm, which is even simpler.

Why not use EOF or something that isn't a number
(for example, 'q') to terminate input?

I'm pretty sure you don't want the compiler doing that work.

Then average remained numbers
Finally print the result

Sounds like a job for printf.

Write some code. If it doesn't work, try to figure
out why. If you can't figure it out, post specific
examples and ask specific questions. Why should anyone
answer your question with more specificity than with
which it was asked?

Probably because dealing with an input stream consisting of numbers /or/
words is more difficult than the original assignment.

I don't think so. Testing for some special but otherwise valid
number is more troublesome than reading numbers while there are
numbers to read:

while (scanf(...) == 1)
/* do something with the number */;

(details omitted because this is homework).
