I have a problem.
When I read from a file I must respect the following rules:
The only characters admitted are :
Number: from 0 till 9
Blank and A....Z (capital letters).
(The not capital letters and the letters with accent are deleted.)
The special letters: ! â€˜â€™ % $ & â€™ ( ) * +, - . / : ; < = > ?
All the others characters will be replaced by blanks.
How could I realize,easily this thing.
