PLEASE WRITE THE COMMENTS FOR EACH LINE OF THE CODE, AND PLEASE USE THE ORIGINAL CODE THAT I GIVE TO YOU. THANK YOU VERY MUCH.

4. Part 2 Structs and Arrays (65 points). In this assignment, we will be making a program that reads in student's information and create a classroom seating arrangement with a number of rows and columns specified by a user. Then it will attempt to assign each student to a seat in an classroom. Use the file homework part 2.c (attached at the end of this document). Complete the file and include all the following requested code in the file homework part 2.c Step 1 First, you need to create a structure student. It should contain two variables, last _name (char [30]) and first name (char [30]). In addition, the following functions should be defined. Function void student init default (struct student *s) Description Assign the default string" ***" to both variables, last name and first name. void student init (struct student *s, char *info) Use the strtok function to extract first name and last name from the variable student, then assign them to each instance variable of the student structure. An example of the input string is David-Johnson void student to string (struct student *s) It prints the initial character of the first name, a dash, the initial character of the last name, and a period. An example of such string for the student David Johnson is: D-J Step 2. You will be creating a structure called classroom seating in the same code file. The structure classroom scating will contain a 2-dimensional array called "seating" of student type. Define the following functions: Description It instantiates a two-dimensional array of the size "rowNum" by "columnNum" specified by the Function void classroom seating init (int rowNum, int columnNum, struct classroom_seating *a) meters inside the struct a. Then it initializes each para student element of this array using the student init default function. So, each student will have default values for its instance variables. int assign student _at (int row, int col, struct classroom seating *a, The function attempts to assign the "s" to the seat at "row" and "col" (specified by the parameters of this function). If the seat has a default student, i.e., a student 4. Part 2 Structs and Arrays (65 points).
