- Computer Science C++ Write a program that: Gets a character array (C-string) using cin.get to allow blanks in the C-string Prints the C-string (what they input) Prints the length (number of characters) in the C-stringSoundex System Soundex is a system that encodes a word into a letter followed by three digtis that roughly describe how the word sounds. That is, similar sounding words have similar four-character codes. For instance, the words carrot and caret are both coded as C123. A slight variation of the Soundex coding algorithm is as follows: 1. Retain the first letter. 2. For the remaining letters, delete all occurrences of a, e, i, o, u, h, y, and w. 3. Replace the letters that remain with numbers so that (a) b, f, p, and v become 1 (b) c, g, j, k, q, s, x, and z become 2 (c) d and t both become 3 (d) l (that is, el) becomes 4 (e) m and n become 5 (f) r becomes 6 4. If the result contains two adjacent identical digits, eliminate the second of them. 5. Keep only the first four characters of what you have left. If you have fewer than four, then add zeros on the end to make the string have length four. Write a program that carries out the algorithm. See Fig. 6.86.sloc) 1. # Given an encoded string, return it's decoded string. # The encoding rule is: k[encoded_string], where the encoded_string# inside the square brackets is being repeated exactly k times.# Note that k is guaranteed to be a positive integer. # You may assume that the input string is always valid; No extra white spaces,# square brackets are well-formed, etc. # Furthermore, you may assume that the original data does not contain any# digits and that digits are only for those repeat numbers, k.# For example, there won't be input like 3a or 2[4]. # Examples: # s = "3[a]2[bc]", return "aaabcbc".# s = "3[a2[c]]", return "accaccacc".# s = "2[abc]3[cd]ef", return "abcabccdcdcdef".

The program outputs the string in which all the digits of the Social Security number and all the characters in the password are replaced by x. (The Social Security number is in the form 000-00-0000, and the user ID and the password do not contain any spaces.) Your program should not use the operator [] to access a string element. Use the appropriate functions described in Table 7-1.
