Binary Search Tree (Insertion, Searching, Display) Multiple Data

Write a Modular C Programming code for Binary Search Tree (Insertion, Searching, Display) Multiple Data DSA

What is Binary Search Tree?

Binary Search Tree is a node-based binary tree data structure which has the following properties:

• The left subtree of a node contains only nodes with keys lesser than the node’s key.
• The right subtree of a node contains only nodes with keys greater than the node’s key.
• The left and right subtree each must also be a binary search tree.

CODE:

#include<stdio.h>

struct student{
    char name[20];
    int roll;
    int marks;

};
struct student hi;

struct node {
    struct student s;
	struct node *left, *right;
};
struct node* root = NULL;


struct node* newNode(struct student* ii)
{
	struct node* temp;
		temp= (struct node*)malloc(sizeof(struct node));
	temp->s = *ii;
	temp->left = temp->right = NULL;
	return temp;
}


void print(struct node* root)
{
	if (root != NULL) {
		print(root->left);
		printf("\nName: %s",root->s.name);
		printf("\tRoll: %d",root->s.roll);
		printf("\tmarks: %d\n",root->s.marks);
		print(root->right);
	}
	return;
}
int search(struct node* node, int key)
{

	if (node->s.roll == key)
		return 1;


	if (key < node->s.roll){
		node->left = search(node->left, key);
		return 1;}

	else if (key > node->s.roll){
		node->right = search(node->right, key);
		return 1;}


	return 0;
}



struct node* insert(struct node* node, struct student* s)
{

	if (node == NULL)
		return newNode(s);


	if (s->roll < node->s.roll)
		node->left = insert(node->left, s);
	else if (s->roll > node->s.roll)
		node->right = insert(node->right, s);


	return node;
}


int main()
{
    int data,no;
printf("Enter the no. of Students: ");
scanf("%d",&no);
for(int i=0;i<no;i++){
        printf("\nEnter Name: ");
        scanf("%s",hi.name);
        printf("Enter Roll No: ");
        scanf("%d",&hi.roll);
        printf("Enter Marks: ");
        scanf("%d",&hi.marks);
    root = insert(root, &hi);
}
    print(root);

    printf("\nEnter Roll No To search: ");
    scanf("%d",&data);

    if(search(root,data)){
        printf("\nFOUND!!!\n");
        exit(0);}
    else{
        printf("\nNOT FOUND!!!\n");
        exit(0);}
    }

OUTPUT

Enter the no. of Students: 3

Enter Name: AAA
Enter Roll No: 123
Enter Marks: 320

Enter Name: BBB
Enter Roll No: 222
Enter Marks: 363

Enter Name: CCC
Enter Roll No: 333
Enter Marks: 965

Name: AAA       Roll: 123       marks: 320

Name: BBB       Roll: 222       marks: 363

Name: CCC       Roll: 333       marks: 965

Enter Roll No To search: 333
