VE482 Project 1

The project have three stages:

• Milestone 1: tasks 1 to 5 must be completed by September 22th;
• Milestone 2: tasks 6 to 9 must be completed by September 30th;
• Final shell: due on October 9th;

You can resubmit your code to test the previous stages, but it doesn't count into grades.
(eg. You can submit both milestone 1 and 2 in stage 2, but only the score of milestone 2 will be admitted.)

If you are using GNU Make and you meet an compile error like

error: implicit declaration of function 'xxx' is invalid in C99 [-Werror,-Wimplicit-function-declaration]

It is because you didn't use the gnu standard of c. Add -std=gnu11 instead of -std=c11 to resolve this problem.
