Please tell me how to fill contents into a hash array dynamically. The hash array is empty initially and it is to be filled with key value pairs (say employee no-employee name from database )so that I can process it later.
My another problem is I would like to get the index of a particular particular character in a string. For example I want to capitalise the first letter in 'abcd.com'. Here I want to capitalise 'a' but I would like to know the way of getting character/text indexes in a string .
