pagesNumbering C++

The C++ code for implementing page numbering can be explained in the following steps:

1. Define the function to calculate the number of digits in a given number.
2. Implement a function to calculate the total number of digits in the given page number.
3. Create a function to calculate the total number of pages based on the total number of digits.
4. Finally, write the main function to test the page numbering implementation.

This approach allows for a modular and structured way of implementing the page numbering functionality in C++.
