Issue
I wrote
while (ptr->next != NULL) {
//code here
ptr = ptr->next;
}
and AddressSanitizer is throwing an heap-buffer overflow error.
I added
if (ptr->next != NULL) {
while (ptr->next != NULL) {
//code here
ptr = ptr->next;
}
}
hoping that maybe it would avoid reading a unallocated address, but now AddressSanitizer is terminating my program with SEGV. I'm not really sure how to fix this as I'm new to programming in C, any insights would be very helpful. Thank you!
Solution
You can do
while(ptr != NULL) {
// code
ptr = ptr->next;
}
or even
for(type* i = ptr; i != NULL; i = i->next) {
// code
}
