Basic Malloc/Free

Question

If I have a snippit of my program like this:

struct Node *node;
while(...){
    node = malloc(100);
    //do stuff with node
}

This means t

Answer 1

then how do I free up all the memory that I have made with all the loops if I only have a pointer left pointing to the last malloc that happened?

You can't. You just created a giant memory leak.

You have to keep track of every chunk of memory you malloc() and free() it when you're done using it.
