Provide the code for the following functions, which will print the IDs of all the nodes inany given binary tree.

struct t_node {

int id;

struct t_node* left;

struct t_node* right;

};

void print_inorder(struct t_node node); // Prints the contents of anentire tree, following inorder traversal.void print_preorder(struct t_node node); // Prints the contents of anentire tree, following preorder traversal.void print_postorder(struct t_node node); // Prints the contents of anentire tree, following postorder traversal.
