Challenge: Concatenate Strings

Problem statement

In the dynamic world of programming, optimizing string operations is a vital skill for developers to master. You are tasked to construct a class template strOps that concatenates a variable number of strings, counts the total number of characters in the concatenated string, and counts the total number of strings combined. Additionally, create a function template display_info to display this information. You also need to create supporting functions to accomplish these tasks.

Note: Ensure that your implementation utilizes variadic templates, fold expressions, and variadic variable templates to achieve the required functionality.

Analysis

We can extract the following information from the problem statement:

• The strOps class: A variadic template class that takes any number of string arguments. It has three member variables.

• The concatenate function: A member function that concatenates the input strings using fold expressions. We can use the following expression to concatenate all the arguments using the + operator.
