When I was reading about Linked list, I came to know that the structure for linked list as
Struct node{
Struct node *next;
int value;
}
Why is the Struct node *next? Why cant it just be an integer pointer? Like below
Struct node{
int *next;
int value;
}
why can’t this hold the next node’s address? Can anyone please give me explanation?
Because then you would be pointing to the address of the next integer. This could be used to retrieve the value of the next int, but nothing more, so from there on onward, you would be stuck.
By linking nodes together, which hold integer values, you can traverse the nodes and retrieve the int values.
