2 Structs Defined Follows Struct Token Int Tokenid Char Tokenname Char Tokenword Token Str Q37145358

I have 2 structs defined as follows:

struct token
{
   int tokenID;
   char *tokenName;
   char *tokenWord;

}token;

and

struct node
{
   char nodeName[8]; // no token name longer than 8characters.
   struct token *token1;
   struct token *token2;
   struct token *token3;
   struct node *child1;
   struct node *child2;
   struct node *child3;
   struct node *child4;
};

In my main I declare a new struct token and initialize it withsome values. When I try to string copy the values from the tokeninto the token1 member of a node like so:

strcpy(node->token1->tokenName,tk->tokenName);

I get a segmentation fault. Any thoughts on why?

Answer

Segmentation faults occur due to a faulty access.
