Write a C program to sort 30 randomly generated uppercase characters in descending order (Z to A). Use the insertion sort algorithm. The program should: a) Generate a random array of 30 uppercase characters b) Print the random array c) Sort the random array using insertion sort d) Print the sorted array In order to achieve the above objectives, you may choose to follow the suggestions below: a) Write a function called generateRandomChar to generate one random character. This function has no input argument but returns a char (i.e. the random character). Call this function 30 times in the main function to generate 30 uppercase characters and assign each of these characters as an element of an array. Hint: Use the function rand() to generate random characters b) Write a function called printArray to print out the contents of an array. The functions input argument is the char array that has to be printed. The function does not return any value. c) Write a function called insertion sort that carries out the insertion sort algorithm. The functions input argument is the char array containing unsorted uppercase characters. The function does not return any value. d) Call the print array function accordingly in main function.

An example of the output is shown in Figure 3. Before: DLQLOHDCWTCBETQWVEPMYISZPGAJTN After: ZYWWVTTTSQQPPONMLLJIHGEEDDCCBA Figure 3
