in c++

Write a program that extracts and displays all vowels in a file.

• Prompt the user for the filename of a text file.
• Read through the entire file and write every vowel to the output file.
  • Do not write consonants or spaces to the file
• Write all line breaks (newlines) from the input file into the output file as well.
• The output filename should be similar to the input file. Use the input filename and preface the name with "vowels_".
  • For example, if the input file is named foobar.txt, the output file should be named vowels_foobar.txt
• Do all of this with a single filestream
• You may not process more than one line of input before writing to the output file
