C Programming Create a program that will display a menu to the user. The choices should be as follows: 1) Enter 5 student grades 2) Show student average (with the 5 grades) and letter grade 3) Show student highest grade 4) Show student's lowest grade 5) Exit Use a switch statement for the menu selection and have it pick the appropriate function for the menu choices. Each option should be implemented in its own function. Initialize the grades randomly between 50-100. So if the user select show student average as their first choice, there will be some random grades in the list already. Function 1: Ask the user for a single grade ans pass it back as a return value. Validate that the grade is in the range between 0-100. Call the function 5 times from the main to place them in the appropriate variable. 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. Function 3: Have this function receive the 5 grades 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. Function 4: Have this function receive the 3 grades as a parameter and returns the lowest grade to the main. The main will use that value to display it. Do not display in this function. Use a loop to repeat the entire program until the user hits 5 to exit.
