Write the function evens whose signature is below. The input to evens is a dynamically allocated array of C$++$ strings and the length of the array. The function evens should create a

new dynamically allocated array containing just the even$-$length strings from the input array. It should

then deallocate the input array and return the array of even$-$length words. You may write helper

functions, but do not use any data structures $($other than string$)$ from the C$++$ standard template

library.

string$*$ evens$($string$*$ words, int len$)$

Note you will need to write a main$()$ function to test your code! $($Consider having one group member

write evens$()$ and another write the test code.$)$ As you write the test code, do you see a flaw in the

design of our program?
