Classwork 11


  • Due: Tuesday, June 1st no later than 1:35pm.
  • Submission instructions: push a commit with the tag classwork11 to your git repository.
  • Deadline reminder: after the deadline passes, you cannot earn any points for this assignment. If the deadline is approaching, submit what you have in order to earn partial credit.

Learning outcomes

  • Practice dynamically allocating memory and freeing it.


Write a program called classwork11.c containing a struct that representing a two-dimensional point. Use malloc to dynamically allocate a point struct. Set the x and y coordinates of your point using the indirect component selection operator ->. Print info about your point, again using ->. Finally, at the end of your program, free the memory using free. A skeleton for your code may look something like this:

#include <stdio.h>
#include <stdlib.h>

# user-defined types
typedef struct {
	# components for point
} point;

int main(void) {
	# declare pointer to a point struct

	# dynamically allocate memory for the point struct that your pointer points

	# set x and y coordinates to values of your choice

	# print info about the point

	# free the memory for the point


Grading - 10 points

  • 1 point - there is a file called classwork11.c in your classwork/classwork11/ directory.
  • The file compiles and runs.
  • Note: you will not earn any points if your work is not committed and pushed to Github with the tag classwork11.

Grading turnaround

This classwork will be graded with scores in Brightspace by 5pm the day it is due (June 1st).
