Write a C program with the following specifications :

Write the definition of a structure named employee that contains character array members for an employees first and last names of size 20, an int member for the employees age, a char member that contains 'M' or 'F' for the employees gender, and a double member for the

employees hourly salary.

Using the above-mentioned definition, write a C program that asks a user to enter the values of 20 employees and save them in an array of employees.

Hint: To define an array that contains 20 elements of type struct employee, you just need to write: struct employee employees[20];

Modify your program to include a function, which calculates the average salary of all employees. The function takes as input the array of all employees and returns the average salary as float value.
