   # gedit helloworld.cc
3. Compile the code.
   # g++ -o test helloworld.cc
4. Run and test the compiled binary.
   # ./test
5. Change the permission of the binary to inexecutable.
   # chmod a-x test
# ./test
6. Make a tarball for submission.
   # tar -cf L1.tar L1
7. Submit your file and check your submission. (checkin/peek/grade)
   For the checkin name, use your recitation session number (R1 for Mon 3pm, R2 for Mon 12pm, R3 for Wed 2pm)
   # ~cs253/bin/checkin L1R# L1.tar
# ~cs253/bin/peek L1R#
