Develop an algorithm that takes as input a string like "A2h;m!Et?", removes all unwanted symbols like punctuators or digits,
and then converts all letters into capitalized form as in "AHMET". Illustrate the algorithm by simple drawings. Then, translate
the algorithm into C code. Also, provide a sample run for proving the correctness of the algorithm

a stack or linked list is not part of the algorithm, those are coding constructs that you might, or might not use. What algorithm have you devised to solve the problem?

We are more than willing to help those that are stuck: but that doesn't mean that we are here to do it all for you! We can't do all the work, you are either getting paid for this, or it's part of your grades and it wouldn't be at all fair for us to do it all for you.

So we need you to do the work, and we will help you when you get stuck. That doesn't mean we will give you a step by step solution you can hand in!
Start by explaining where you are at the moment, and what the next step in the process is. Then tell us what you have tried to get that next step working, and what happened when you did.

As with your other question (which I assume you have now completed) you need to follow the instructions, which are fairly clear.
Something like:

Create a destination array, at least as big as the source.
For each character in the source:
  - if it is an alphabetic character, convert it to upper case if necessary
  - copy it to the next position in the destination.
  - if it is not alphabetic ignore it.

Not really too difficult. ~~You could overwrite the original source rather than create a new array if you wish.~~
