Question #8362
Write a C++ program that asks the user to enter a number n followed by n words. These words will be stored in an array. The program will read the content of the array and make the following changes:
‐ The words that have 4 characters or less will be changed by the word invalid
‐ The words that have 5 characters or more will be transformed as follows: The first and the last characters will remain the same. However, the other characters will be transformed into stars(*) The program will display at the end the new content of the array as well the percentage of words that have been changed into the word invalid.
