Please solve using C++ program step by step code and a screenshot for the output of the program

3. Something went horribly wrong with the encrypted document backup process at the college and all files were converted to strings containing 1s and 0s representing the binary representation of the file. Write a program to restore all the files. All the original files were in 16-bit Unicode. Input from a text file containing a long string of 1s and 0s whose length is guaranteed to be a multiple of 16. Output to the screen the original file contents. Let the user input the file name from the keyboard. Refer to the sample output below. Sample File:

(The actual input file contains only one line which appears to span many lines here in the problem.)

Sample Run: Enter file name: expansion.txt This is the original file.

Good thing you recovered it!

Name the program: DeExpansionXX.cpp or DeExpansionXX.java, where XX are your initials.
