Write a program that reads a number between 0 and 999,999,999,999 from the user, where the user enters a comma in the input. Then print the number without a comma. You should assume the user will give you a number with the commas where they should be.

You will want to work with the number as a string! You will need to use string member functions length and erase. Note: You may not use atoi, stoi, stod, stof, sstream, from_chars, or any other conversion functions in the std. No loops! No includes other than iostream and string.

***Please use C++. Thank you!***
