Java Program to Print Half Diamond Star Pattern
In this article, we will understand how to print half diamond star pattern. The pattern is formed by using multiple for-loops and print statements.Below is a demonstration of the same −InputSuppose our input is −Enter the number of rows : 8OutputThe desired output would be −The half diamond pattern : * ** *** **** ***** ****** ******* ******** ******* ****** ***** **** *** ** *AlgorithmStep 1 - START Step 2 - Declare three integer values namely i, j and my_input Step 3 - Read the required values from the user/ define the values Step 4 - We iterate through two ...
Read MoreJava Program to Make a Simple Calculator Using switch...case
In this article, we will understand how to construct a simple calculator using switch-case. The switch statement evaluates an expression, matching the expression's value to a case clause, and executes statements associated with that case.Following are the arithmetic operations we are going to perform.AdditionSubtractionMultiplicationDivisionFloor DivisionModuloBelow is a demonstration of the same −InputSuppose our input is −The two inputs: 40.0 and 12.0 Operator:%OutputThe desired output would be −The result is 40.0 % 12.0 = 4.0AlgorithmStep 1 - START Step 2 - Declare three values namely my_input_1, my_input_2 and my_result and declare a character value namely operator. Step 3 - Read the required ...
Read MoreJava Program to pass method call as arguments to another method
In this article, we will understand how to pass method call as arguments to another method. We can call a method from another class by just creating an object of that class inside another class. After creating an object, call methods using the object reference variable.Below is a demonstration of the same −InputSuppose our input is −Enter two numbers : 2 and 3OutputThe desired output would be −The cube of the sum of two numbers is: 125AlgorithmStep 1 - START Step 2 - Declare two variables values namely my_input_1 and my_input_2 Step 3 - We define a function that takes ...
Read MoreJava Program to Print Pyramid Star Pattern
In this article, we will understand how to print pyramid star pattern. The pattern is formed by using multiple for-loops and print statements. Below is a demonstration of the same − Input Suppose our input is − Enter the number of rows : 8 Output The desired output would be − The pyramid star pattern : * * * * * * * * * * * * * * * * ...
Read MoreDelete an element from array using two traversals and one traversal in C++?
Two Traversals Let us first define the original array and the element to be searched and deleted from the array −int ele = 5; int arr = [1,2,3,4];Now we loop in the array to find the given element −for (i=0; i
Read MoreDelete array element in given index range [L – R] in C++?
Let us first define the original array and the exclusive range for deletion of the array elements and also find the original array length −int arr[] = { 2, 4, 6, 8, 10, 12, 14, 16, 18, 20}; int L = 2, R = 6; int length = sizeof(arr) / sizeof(arr[0]);Now we loop in the array and if index position (i) is greater than L or R we increment the variable k which will be used to shift positions(delete) of array element once the index value (i) lies between the range L and R. Also, the new length of the ...
Read MoreDelete leaf nodes with value as x in C++?
Let us first define the struct that would represent a tree node that contains the data and its left and right node child. If this is the first node to be created then it’s a root node otherwise a child node.struct Node { int data; struct Node *leftChild, *rightChild; };Next we create our newNode(int data) function that takes an int value and assign it to the data member of the node. The function returns the pointer to the created struct Node. Also the left and right child of the newly created node are set to null.struct Node* newNode(int ...
Read MoreDelete leaf nodes with value k in C++?
Let us first define the struct that would represent a tree node that contains the data and its left and right node child. If this is the first node to be created then it’s a root node otherwise a child node.struct Node { int data; struct Node *leftChild, *rightChild; };Next we create our newNode(int data) function that takes an int value and assign it to the data member of the node. The function returns the pointer to the created struct Node. Also, the left and right child of the newly created node are set to null.struct Node* newNode(int ...
Read MoreDeleting a binary tree using the delete keyword in C++?
Let us first define our binary tree using a class containing int data, btree_node * rightChild, btree_node * leftChild. The leftChild and rightChild are pointers to btree_node. All the members in our class are public.class btree_node { public: int data; btree_node* leftChild; btree_node* rightChild;For creating a new node we have the constructor function that takes the int value as parameter to assign it to the newly created node value. The leftChild and rightChild are set to null.btree_node(int data){ this->data = data; this->leftChild = NULL; this-> = NULL; ...
Read MoreDemlo number (Square of 11...1)" in C++?
Demlo numbers are palindromic numbers that are generated by the square of number of form 11..1 given that the number is less than 10 digits.Let us first declare the string variables −string demNum = "1111"; string square = "";Now, we loop till the length of the demNum string. Inside the loop we convert the index value i to string and append it to square variable.for(int i=1 ;i= 1; i--) square += char(i + '0');ExampleLet us see the following implementation to get a better understanding of demlo numbers −#include using namespace std; int main(){ string demNum = "1111"; ...
