Code the given C++ function. ```cppstring evenIndex(string s){ //return a string formed by the characters at even index (0,2,4,...) of the string s}```### ExplanationThis snippet is a C++ function named `evenIndex` that takes a single parameter `s` of type `string`. The function is intended to return a new string composed of characters from the original string `s` that are at even indices. In zero-based indexing, even indices are 0, 2, 4, and so on. However, the implementation of this logic is missing and should be added within the curly braces.
