struct NUMBERS
{
    char name[MAXCHARS];
    struct NUMBERS *value;
};

i am new to programming ...can anyone explain this for me ?

Edited 5 Years Ago by Narue: Added code tags

This is defining a custom data type; a structure of type NUMBERS.

This newly defined data type contains two sub-objects. This first of these sub-objects is an array of chars, labelled "name". The array is MAXCHARS long.

The second sub-object is a pointer named value. It is a pointer to objects of type NUMBERS, which is a struct.

This does not actually create any new objects; it just defines what one of these new objects will look like when you do actually create one. You would then create one as follows:

struct NUMBERS anInstance;

and then access the internal objects like this:

anInstance.name[0] = 'A';for example.

Ummmm this is called self refrential structure which is basically nothing but referring to a structure of its own type.

struct node {
    int data;
    struct node *next;
};

In the code above , a pointer is used . Pointer is used for storing either a valid address or NULL.
here next is a pointer which will store some address which is of struct node type .
for eg.
in the code:-

int a=5;
int *b;
b=&a;

b is a pointer which will store the address of any integer data.
similarly with *next , it will store the adress of that element whose memory block have an integer space and a space for storing of address of struct node type.

Ummmm...

There's no need to type everything you say. You can leave out the "Ummmm" at the beginning.
