Question

Write a function that, given a word and a set of characters, filters all occurrences of those characters from the word.

For e.g. remove_chars("abcdeeeeefmnop", "ebo") returns: acdfmnp i.e all occurrences of e, b and o have been removed from abcdeeeeefmnop

You should acquire the word and set of characters both from the user and then pass them to the function.

Note: std::cin terminates when it encounters a space, you should take the word and character set as separate inputs: std::cin >> word >> charset; Where word and charset are arbitrarily named variables to store the word and character set.

Hint: You can use substr(i, l) function where i is the index into the string and l is the number of characters to extract. It would be easier if you stored the output in a separate variable. Write this function recursively. Do not use any loops.

Hint: You will need to create a helper function (also recursive) that checks if any given letter in the word is present in the charset. This function can be prototyped as follows: bool contains(string letter, string charset)
