In Worker class,it includes two field, nYearWked and curSalary, and constructor$($s$).$ It definesthe CalcYearWorked$()$ function using $($current year $$ yearStartedWked$)$ and saveit in the nYearWked variable. It also defines the CalcCurSalary$()$ function thatcalculates the current year salary by using initial salary with $3\%$ yearlyincrement.

Create a Manager class that is derived from Worker class.

In Manager class,it includes one field: yearPromo and constructor$($s$).$ Itincludes a CalcCurSalaryfunction that calculate the current year salary by overriding the base classfunction using initial salary with $5\%$ yearly increment plus $10\%$ bonus. Themanager$$s salary calculates in two parts. It calculates as a worker before theyear promoted and as a manager after the promotion.

Write an application that reads the workers and managers information from files $($worker$.$txt$$ and $$manager$.$txt$)$ and then creates the dynamic arrays of objects.
