Solve in C++ Write a program that reads a file and removes all commas from it and writes it back out to a second file. It should print to the console window, at the end, the number of commas removed.

The program needs to:

- Prompt the user for the name of the file to read.

- If the file is invalid, asks the user again to enter a valid file.

- Reads file and removes the commas

- Write the non-comma characters to output.txt, including all spaces.

- When done reading the input file, write the total number of commas removed to the console window.

For example, if the input file contains 3+,2=5m, 7%,6=1 hello

Then the output.txt file should contain:

3+2=5m 7%6=1 hello

And the console window should print Removed 3 commas.
