Based on Problem P11.4 Modify the merge sort algorithm to sort a vector of Employees by salary. The class Employee in this problem is assumed to be class Employeet public: Employee (string e_name, double e_salary) : name (e_name), salary (e_salary) t ) string get_name () const f return name; ) double get_salary () const return salary; ) protected: string name; double salary; Write a program that reads the list of people's records from a file data2.txt, creates a corresponding vectorEmployee> and displays the name and salary for each employee After that the program should sort vector and display the name and the salary of employees in the sorted vector (for details see IO sample below) . You can assume that data for each employee is stored in data2.txt as name I salary one data record per line) and that the file has at least one line
