Question

Please include function in this program

Write a C program that will calculate the gross pay of a set of employees utilizing pointers instead of array references. You program should continue to use all the features from past homeworks (functions, structures, constants, strings). The program should prompt the user to enter the number of hours each employee worked. When prompted, key in the hours shown below. The program determines the overtime hours (anything over 40 hours), the gross pay and then outputs a table in the following format. Column alignment, leading zeros in Clock#, and zero suppression in float fields is important. Use 1.5 as the overtime pay factor. This week, adding a Total and Average row is no longer optional, its required for this assignment: a) Add a Total row at the end to sum up the wage, hours, ot, and gross columns b) Add an Average row to print out the average of the wage, hours, ot, and gross columns Name Clock# Wage Hours OT Gross Connie Cobol Mary Apl Frank Fortran Jeff Ada Anton Pascal 098401 526488 765349 034645 127615 10.60 9.75 10.50 12.25 10.00 51.0 42.5 37.0 45.0 40.0 11.0 2.5 0.0 5.0 0.0 598.90 426.56 388.50 581.88 400.00 Total: Average: 53.10 10.62 215.5 43.1 18.5 3.7 2395.84 479.17 You should implement this program using a structure similar to the suggested one below to store the information for each employee. Feel free to tweak it if you wish. For example, its OK to have a first and last name member instead of just a name member, and if you want to use different types, that is OK as well. struct employee char name [20]; long id_number; float wage; float hours; float overtime; float gross;
