6.9 Lab: Word Filter In this lab you will write a program that reads in a text tile containing a list of words, and writes two text files; one containing words with an even numiber of characters, the other containing words with an cdd nuriber of characters The program should begin by prompting the user for the name of the input file Validate the filename to make sure it ends in.txt. If it does nct, re prompt the user after printing an informative message. For example: Enter the na of the input file: wozds.dec Only filenames ending in '.txt' are accepted! Enter the name of the input file: The program should attempt to open the file for reading If there is an error (for example, if the file does not exist), then the program should output an error message and exit (by returning 1 from main). For example Enter the name of the input rile: no such file.txt Failed to open file for road: no such filo.txt Assurriing the file opens successfully, the program should prepare the two output files. These files should be named: -even.txt -odd.txt where is the filename up to, but not including,.txt Fcr example, if the user enters words.txt as the input file name, the corresponding output file names will be words even.txt and words odd.txt The program should now use a while loop to read in the words, count the number of characters, and write the words to the appropriate output file, each word on a separate line. Keep counts of how many words are read and written so that you can output a sumrnary at the end As an example, suppose the input file is numbers.txt which contains three Iour aight. nine The result of a program run should look like this: Enter tha name of the inplit fila: nimh rs.txt 10 words raad in from nimhera.txt 3 words written to numbers-even.txt 7 words written to numbars-odd.txt The program should generate numbers-even.txt four nine and numbers-odd.txt three aight ten Hints 1) Use arile loop to valdate the fiename input. 2a) Use.find) to lccate the position or a. txt" the filename. h) Remember, the specia value string : : npos is returned from .find()there is no match 3) The.insert() method inserts a substring into a string at a given index. 4) The.size) (or.Length()) method can be used to detmine the length of a string 5) ne mod (%) operator can be used to determine tr a number is even or odd
