A. Write a C++ program that creates a class called "Employee" with one data member called "skills." You must enter various skills from the user and save them in the text file "skill. txt." B. Create a read() method that reads data from the “skill. txt” file and saves the unique skills name in a string or char type vector.
C. After all of the unique skills have been stored in the vector, ask the user for a "skill name" and see if the skill has already been stored in the vector.
D. If the skill has already been saved, display the message "The input skill has already been added," and if the skill has not been recorded in the vector, store it.
