What are automation Scripts?               A code that can be reusable to execute a function in multiple times. It automatically executed without any user intervention. In python, it is stored with ‘.py’ extension. Steps to execute the automation scripts: 1.Python Installation ·        First, make sure that system has python. ·        Just check the version in command prompt. ·        Open the command prompt by giving ‘cmd’ command in search panel. ·        It opens the command prompt. ·        Use the below syntax to check the version. C:\Users\rajeswari jeevananth>python --version Python 3.10.0 2. Set up your Environment for windows ·      Create a project folder. 3. Create the automation script     ...

               It is a classical project. It is implemented by the use of graph traversal algorithm. It mainly finds the path from starting point to the end point. Here, maze is represented as a 2D matrix. Walls are marked as 1 and paths are marked as 0. C implementation: ·        It starts from including header file. ·        First, the rows and columns are defined as 5. ·        Maze is initialized with values. ·        Visited value is created. ·        solveItMaze() function is used to solve the maze. ·        This function is used to visit all the rows and columns to find the path. The path starts from starting point to end point. ·        Main() function checks for path is not equal to 0,0. ·        ...

               Let us create a simple project for Student Information System. It uses a Linked list and Binary Search Tree. //   First, a student structure is created with rollno, name ,marks and a pointer next. #include <stdio.h> #include <stdlib.h> #include <string.h> // Let us   create Student structure typedef struct Student {     int s_rollno;     char s_name[50];     float s_marks;     struct Student *next;    // Self Referential structure } Student; // BST Node structure is created typedef struct BST_Node {     Student *student;     struct BST_Node *left, *right; } BST_Node; Student *head = NULL;    // Linked List head is assigned as NULL BST_Node *root = NULL;    // BST root // create function to memory allocation Student* createStudent(int roll, char nam...

     This is the next type of graph representation. In the previous post, the adjacency matrix is used to represent the graph. You can visit the below link to access the adjacency matrix. https://rajeeva84.blogspot.com/2026/05/representation-of-graph-using-adjacency.html It makes use of linked list . It uses vertexes. It   #include <stdio.h> #include <stdlib.h>   struct g_Node {     int g_vertex;     struct g_Node* g_next; }; struct Graph {     int num_Vertices;     struct g_Node** adjLists; }; // let us Create a node struct g_Node* createNode(int v) {     struct g_Node* newNode = malloc(sizeof(struct g_Node));     newNode->g_vertex = v;     newNode->g_next = NULL;     return newNode; } // here, is the graph code struct Graph* createGraph(int vertices) {     struct ...

              Graph is a non-linear data structure. It can be represented by adjacency matrix or adjacency list. Let us discuss the methods in detail. This blog post deals with the first method Adjacency matrix. Adjacency matrix:               It is a two-dimensional matrix.it deals with the edges present between nodes.   If the edges found, it assigns the weight as 1. Otherwise, it values it as 0. Code implementation: This code includes the built-in header file. It defines the vertices as 4. A function ‘Display_Matrix()’ is used to represent the graph. ‘main()’ function initialises the graph. It assigns the value for matrix.  Finally,it calls the ‘Display_Matrix’ function to display the output. Code: #include <stdio.h> #define V 4   // Declare the number of vertices void Display_Matrix(int graph[V][V]) {     for (int i = 0; ...

               Binary tree is a tree which has two nodes. It has a root node. It has a left sub tree and right sub tree. Let us implement the c program to count the leaf nodes and height of a binary tree. C implementation:               This implementation starts by including header files. Next, declare the node structure for tree. It has node with data, left and right values. Now, a new node is created by allocating its memory. The values are initialised.   To calculate the heights of the tree, traverse the tree. To count the leaf nodes, check the root nodes, traverse each sub tree separately and count the nodes. In the main() function, create the root node and all child nodes by using the newNode() function. Call the height() function and countLeafNodes() function to display the output. C Code: #include <stdio.h> #include <stdlib.h> // D...
