Struct variable

Question

When we have :

struct node {
    char...
    int....
    struct node *....
}

typedef struct node Node;

and then we have a function like this:

int function(Node f){...}

What is this f ?

f is a variable of type Node, which is essentially same as the type struct node. — Sourav Ghosh

f is an input argument of the type Node. The type Node is synonym of the type struct node.

alias is probably a better choice over synonym for describing what Node is.

In the statement typedef struct node Node; you are giving alias name of struct node as Node by using typedef.

So in the definition of function()

int function(Node f){...}

f is nothing but variable of struct node type.

Also you can see the typedef declaration and meanings here http://en.cppreference.com/w/c/language/typedef
