Assignment

  • Log in to the server.
  • From your home directory, navigate to csci112_spring2024/classwork/week12/fri/, creating directories week12 and fri if necessary.
  • Copy main.c, planet.c, sort.c, planet.h, sort.h, and Makefile from /public/classwork/week12/fri/.

Fill in the TODOs in main.c so that when you compile and run the program, you get:

[g73x595@csci112 fri]$ make
gcc -c main.c -Wall
gcc -c planet.c -Wall
gcc -c sort.c -Wall
gcc main.o planet.o sort.o -Wall
[g73x595@csci112 fri]$ ./a.out
