What is the size of a node? and where are the data recorded?
advertisements
As the question implies,what's the size of usual node:
struct node{
int data;
node* next;
};
If the struct holds the data and the address of next node, what's the size of the pointer address(not what it points to)? Is there a difference if the next points to NULL?
where is the data(which is not a pointer) saved, stack or heap, if I made "new node":
node* linkednode= new node;
Are the answers change if I made class node?
You can easily check those using the sizeof() function applying it not only to your int and pointer variables but for the node itself. Usually ints and pointers are 4 bytes on 32 bit platforms, so this is implementation defined and might vary on other platforms. The total size of node might be equal to 8 but might not due to the cause specified above and\or data alignment.
