Improve the following code using typedef. struct node { int data1; float data2; struct node *left; struct node *right; }; struct node *ptr; ptr = (struct node *) malloc (sizeof (struct node) );

Correct Answer: typedef struct node * treeptr typedef struct node { int data1; float data2; treeptr *left; treeptr *right; }treenode; treeptr ptr; ptr = ( treeptr ) malloc ( sizeof ( treenode ) );
