- Please use git clone https://github.com/hercule24/EECS-343.git to clone this repository, then you can begin to write your part of code, BEFORE PUSH, please do a "git pull --rebase" to make sure you are pulling the latest change by others without merging, this will keep the commits history linear, then do a "git push" to push your code.
- Please conform to the styles in the skeleton, such as indentation, as this will make others life easier.
- Please write reasonable, self-explanatory commit messages.
Project 1 has included a sample code as TA has shown in discussion class. So do read the sample code as to understand the basics.
This project deals with pointers a lot. If you declare a pointer for later use, please make it equal to NULL, like the following.
int *p = NULL;
Before you dereference the pointer when you traverse the linked list or do some other things, make sure it doesn't point to NULL, like the following:
while (p != NULL) {
Node *next = p->next;
}
or:
if (p != NULL) {
Node *next = p->next;
}
After you use the pointer, if the pointer will be used in the future, please make it also equal to NULL. Because in this way, you can later check if this pointer is NULL or not before dereference it.
p = NULL;
All the above efforts are to prevent the notorious segmentation fault, I hope we won't spend to much time debugging seg fault.
