Write a program that reads in a line consisting of a student's name, social security number, user ID, and password. The program outputs the string in which all 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 000-00-000, and the user ID and password do not contain any spaces.) The prgram should not use the operator[ ] to access a string element. Make sure to include an IPO Chart and pseudocode.
