Write the function processName(). It's input is a full name in the form (First MI. Last). Your job is to use string member functions to break the name into the first name, last name and middle initial, and return the processed name in the form "Last, First Ml.". Use the string member functions substr( ), find( ), rfind( ), find_first_not_of(), find_last_not_of( ) and at () to solve this problem. You may assume: - that every name will have exactly one word for the first and last names and a single character, followed by a period for the middle initial. - There will be at least one space separating each of the portions of the input name, but there may be more spaces. main.cpp
