Write a C program that will calculate the gross pay of a set of employees utilizing pointers instead of array refernces.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 columnsb) 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 098401 10.60 51.0 11.0 598.90 Mary Apl 526488 9.75 42.5 2.5 426.56 Frank Fortran 765349 10.50 37.0 0.0 388.50 Jeff Ada 034645 12.25 45.0 5.0 581.88 Anton Pascal 127615 10.00 40.0 0.0 400.00 --------------------------------------------------------- Total: 53.10 215.5 18.5 2395.84 Average: 10.62 43.1 3.7 479.19 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; }; Set a pointer to it and then use that pointer going forward to access elements (and their associated members) in your array of structures. Again, do not use array references with indexes (use emp_ptr->hours ... not ... emp [ i ].hours as the latter is not a fast).Use the following information to initialize your data.

Initialize the array with the data provided and reference the elements of the array with the appropriate subscripts.Do not use any array references with indexes. For example:emp[i].wage /* this is bad, it uses an array reference with an index, in this case, i */emp_ptr->wage; /* this is good, it uses a pointer to reference the wage value */Here is template************************************************************************/ /* */ /* HOMEWORK: 7 */ /* */ /* Name: Joe Student */ /* */ /* Class: C Programming, Cybercourse */ /* */ /* Date: <add your date> */ /* */ /* Description: Program which determines gross pay based on overtime */ /* and outputs a formatted answer.
