In this assignment you will implement a class called string_class. Place the class declaration in the file string_class.h"and the class implementation in the file "string_class.cpp". The class has the following characteristics 1. A private string variable "current_string. 2. A default constructor that sets current_string" to an empty string (). 3. An explicit-value constructor that sets current_string equal to the argument that is passed to the explicit-value constructor when a string_class object is declared. 4. A public member Boolean function called palindrome that returns true if the current_string reads the same forward as it does backwards; otherwise it return false. For example madam, 463364, and ABLE WASI ERE I SAW ELBA are all palindromes. 5. A public member void function called replace_all that accepts two string arguments, old_substring and new_substring. The function will replace each occurrenceof old_substring with new_substring in "current_string". For example, when the function is invoked, if current_string = aaabbacceeaaa, old_substring="aa", and new_substring=zzz, then after execution of the function, current_string= zzzabbacceezzza. Note special cases: If current_string is empty, or if old_substring is larger than current_string, or if old_substring is not located in current_string, then the value of current_string will not change. DO NOT USE THE STRING CLASS FUNCTIONS find, replace, orsubstr. 6. Overload the insertion operator(
