code a program in C.

Create a program that display a menu to the user. The choice should be as follows: Enter 5 grade Show average (with the 5 grades) and letter grade Show highest grade Show lowest grade Exit If you want to put the menu into a function you may. The program should use a switch statement for using the appropriate function based on the user's choice. Each option should be implemented int its own function (use appropriate names for the functions). Initialize the variables for grades randomly between 50-100 so if the user selects show average as their first choice, there will be some grades in the variables already. You should have the following functions: In ONE OF them you should traverse the array using pointer notation. Function 1: This function is responsible for getting the 5 grades at once and placing them into the array. Validate that the grades are in the range between 0-100 (use a loop). (use pointer notation to traverse the array) Function 2: Calculate the average of the 5 grades passed in and display the average with 1 decimal place and also display the letter grade. Average Letter Grade 90 - 100 A 80 - 89 B 70 - 79 C 60 - 69 D Below 60 F Function 3: Have this function receive the array as a parameter and returns the highest grade to the main. The main will use that value to display it. Do not display in this function. (use pointer notation to traverse the array) Function 4: Have this function receive the array as a parameter and return the lowest grade to the main. The main will use that value to display it. Do not display the function. (use pointer notation to traverse the array) Use a loop to repeat the entire program until the user hits 5 to exit.
