In this exercise you will create a program that will be used in a digital library to format and sort journal entries based on the authors last name. Each entry
has room to store only the last name of the author.
Begin by removing the first name "Isaac" from the string variable journal_entry_1 by using the string function erase. Do not forget to also remove
the whitespace so that the string variable journal_entry_1 will then contain the string "Newton" with no whitespaces.
The journal entries should be sorted alphabetically based on the authors last name. For example, the last name "Brown" should come before the last
name "Davis".
Create an if statement so that if the last name contained within journal_entry_2 is alphabetically less than the last name contained within
journal_entry_1, then the string values are swapped using the string function swap.
You may use either of the comparison operators <> in the if statement but remember that following ASCII, "A" is lexicographically lower than "B".
Utilize the below two strings in your solution
string journal_entry_1 {"Isaac Newton"};
string journal_entry_2 {"Leibniz"};

Program Purpose - Professional Athletes often hire other professionals to help take care of matters for them. We will group them in four categories: Lawyers, Personal Assistants, Agents, and Trainers. They all get paid a percentage of the athlete's total yearly salary. Lawyers - 10%, Personal Assistants - 3%, Agents - 7%, and Trainers - 5% . Prompt the user to enter the athlete's salary for the year (ensure that the entered value is positive). The user should then enter the name and category of each of the hired professionals. The athlete should be able to hire as many professionals in each category as he/she wants, even if it is more than he/she can afford. Based on the category, calculate the amount that each professional should be paid. After all data has been entered, print the names of each professional hired, how much each is being paid, the total amount the athlete paid, and how much the athlete has left.
