simple program

Need a simple program created for an assignment. Must be created in Codeblocks. Unit3: Simple Grade Book This program should use an array to store percentage grades in the range from 0 to 100 (inclusive). The program should allow the user to indicate when he or she is done entering grades. When the user is done entering grades, the program should print out the grades entered. Your C code must be both well-formatted and well-commented. Be sure to include extended comments about the loop used in your code. Part 1: Simple Grade Book, Version 1.1 Modify the grade book code from Unit 3 so that it uses heap memory to store percentage grades in the range from 0 to 100 (inclusive). The program should allow the user to indicate when he or she is done entering grades (since the user may not have grades to fill the whole array). When the user is done entering grades, the program should print out the grades entered by the user. Be sure to free the head memory before the program ends. Part 2: Simple Grade Book, Version 2.0 Modify the grade book code from Unit 3 so that it uses custom functions to add grades to the array, print the grades entered, calculate the average grade (arithmetic mean, not letter grade), and report the highest and lowest grade entered. This version of the program does not need to use heap memory, though you are welcome to do so. The program should allow the user to indicate when he or she is done entering grades (since the user may not have grades to fill the whole array). When the user is done entering grades, the program should print out the grades entered by the user. The program should also display the average grade, highest grade, and lowest grade. *Be sure to include extended comments to explain the roles of your custom functions. *Be sure to include extended comments about the loop used in your code.
