Modify this C++ Program by adding the following:

Change from one employee to n employees. Read the value of n from a keyboard (it should be at least 3) and validate it using a while loop. Its value should be in the range of 1 and 5.

All the variables and names constants must be declared in the beginning of the program. Use named constants for storing the weights.

Read rest of the input from the Input File and validate all input data. Report should be based on three years evaluations. It means that you will be using a nested for loop. The outer loop will be on employees and the inner loop will be on years. You will be computing and writing in the report each years Final Weighted Evaluation, Total Final Weighted Evaluation (total of all three years), and Average Final Weighted Evaluation (average of all three years). Use the Average Final Weighted Evaluation (AFWE) to determine appreciation/warning letters as follows:

o If the AFWE is < 70, Report should include a warning letter (store the content of the letter in the Input File and read it from the Input File.)

o If the AFWE is >= 95, Report should include an appreciation letter (store the content of the letter in the Input File and read it from the Input File.))

Report should include current salary, salary raises (in % as well as in dollars), and salary with the raise. Use the Average Final Weighted Evaluation (AFWE) to determine the salary raise as follows:

o If the AFWE is < 75, Salary Raise = 0%

o If the AFWE is > 75 but < = 80, Salary Raise = 1%

o If the AFWE is > 80 but < = 90, Salary Raise = 3%

o If the AFWE is > 90 but < = 100, Salary Raise = 5%

o If the AFWE is > 100, Salary Raise = 10%

Since all the other data (except the value of n) is read from the input file, use if statements to validate the data. Strings should be validated for their lengths in the range of 1 to 50 (use length member function, to compute the string length); integer numbers should be between 1 and 100; and floating point numbers should be between 1.00 and 1000.00.

In the validation of the data, if the non-numerical data is not correct, print a statement about it and use continue statement to skip the current iteration. If numerical data is not correct, print the warning about this data and use break statement to terminate the loop.

Write all the Output to the Output File.

Create your own data in the input file (except the value of n which you are reading from the keyboard as described above) before running the program

A new sample Input/output for one employee is provided below. Your report will have at least three employees
