need help with tricky string modyfication

Jul 29th, 2007

Let's assume that the 100th user inputs his name as: Jackson Michael.

I would like my prog to print to the file the reference, which would be combining the first letter of the lastname with all the consonants remaining after removing all vowels (a,e,i,o,u).

in case of Jackson it would be: JCKSN100

any ideas how to accomplish that? as of right know all the inputted names are in an array and each element is a plain string.

Thanks in advance

Perhaps begin with a function called 'isVowel()', which returns true or false, depending on the type of letter passed to it.

Then implement your own 'strcpy' like function, which makes use of isVowel()

I would convert all the characters to upper case first, using toupper()

Given a string without undesirable characters like '\n', etc...

Thanks man, by the time I checked I got ready almost the same thing except I used if instead of switch. Very much appreciated.

Best Regards

You're welcome. I don't know if that is how professionals would do it,
but that's one way I would.

More homework on a plate, very disappointing

You should have waited more than 5 minutes to see what the OP could come up with before blurting out an answer.

So instead of the OP getting to practice the all important analytical and problem solving skills, they're going to have to try to practice them on the next problem instead (only that will be so much harder now).

Oh well, nevermind, no great loss I suppose.

I appreciate the concern but like I mentioned before I came up with basically the same thing, only I used if statement instead of swicth.
