2.6 Task 6 You are tasked to create a software to compare the current staff salary with expected salary. All of the tasks (a) to (d) should be done in the function "calculate_salary_difference ()". The formula to calculate expected salary is as follows: Expected salary = basic* (1.1)(years in company) where basic = RM2,500. The salary difference is Salary difference Expected salary - Actual salary a. [4 marks] Modify the function "calculate_salary_difference ()" to calculate the difference of expected salary and actual salary of each staff. The difference should be calculated as Salary difference = Expected salary - Staff Salary. b. [2 marks] Modify the "StaffInfo" structure to include expected salary and salary difference for each staff information as elements of the structure. c. [5 marks] In the file you created, print the Full Name, Salary and Salary Difference of all staff, including the newly entered staff in Task 5. Format the file so the information is readable. Use your creativity to print the result in the file to make it readable.
