In c++ please

func- 15. Write a function that determines if two strings are anagrams. The tion should not be case sensitive and should disregard any punctuation or spaces. Two strings are anagrams if the letters can be rearranged to form each other. For example, "Eleven plus two" is an anagram of "Twelve plus one." Each string contains one "v"', three "e's", two "l's", etc. Test your func- tion with several strings that are anagrams and non-anagrams. You may use either the string class or a C-style string
