Question

Code the C++ function given below.

```c string evenIndex(string s) { // return a string formed by the characters at even index (0, 2, 4, ...) of the string s } ``` This code snippet defines a function named `evenIndex` that takes a string `s` as an input. The purpose of this function is to return a new string composed of characters from the input string located at even indices (0, 2, 4, ...). The function currently contains a comment explaining its intended functionality but lacks the actual code implementation to achieve the described result.

Expert Solution
Explanation

Here I have created a function named evenIndex().

In this function, I have used a for loop to iterate over the string, with the increment of 2 so that it gets to the even index only.

Inside the loop, I have extracted the characters from the string and added them to form the new string.

Then, I have returned the new string.

Next, in the main method, I have taken input from the user and stored it to a variable.

Then, I have called the function inside the print statement to get the result.
