Program DescriptionPrint the natural numbers columns wise as show below1 2 6 3 7 10 4 8 11 13 5 9 12 14 15Algorithmi stands for rows and j stands for columns. 5 stands for making pattern for 5 Rows and Columns Loop for each Row (i) K is initialized to i Loop for each Column (j) Do the Pattern for the current Column (j) Display the Value of K Reinitialize the Value of K = k + 5 - jExample/* Program to print the Natural Numbers in Columns wise */ #include int main(){    int i,j,k;    printf("Printing the Numbers in Columns wise: ");    printf("");    printf("");    for(i=1;i

Program DescriptionA numerical pattern is a sequence of numbers that have been created based on a rule called a pattern rule. Pattern rules can use one or more mathematical operations to describe the relationship between consecutive numbers in the sequence.Examples for PatternsPattern 11 2 6 3 7 10 4 8 11 13 5 9 12 14 15Pattern 2 1 1 2 3 1 2 3 4 5 1 2 3 4 5 6 7 1 2 3 4 5 6 7 8 9 1 2 ...

Program DescriptionThe square of a number is that number times itself.A square number or perfect square is an integer that is the square of an integer;The perfect squares are the squares of the whole numbers1, 4, 9, 16, 25, 36, 49, 64, 81, 100Here are the square roots of all the perfect squares from 1 to 100.√1 = 1 since 12 = 1 √4 = 2 since 22 = 4 √9 = 3 since 32 = 9 √16 = 4 since 42 = 16 √25 = 5 since 52 = 25 √36 = 6 since 62 = 36 √49 = 7 since 72 = 49 √64 = 8 ...

Program DescriptionPrint multiplication table of a given numberAlgorithmAccept any number from the User for which we need to form multiplication table.Multiply the given number starting with the value of I (=1)Multiply the given number by incrementing the value of I till the I value is lesser than or equal to 12.Example/* Program to print the multiplication table of a given number */ #include int main() {    int number, i;    clrscr();    printf("Please enter any number to find multiplication table:");    scanf("%d", &number);    printf("Multiplication table for the given number %d: ", number);    printf("");    for(i=1;i

Program DescriptionIt is a quadrilateral where both pairs of opposite sides are parallel.There are six important properties of parallelograms to knowOpposite sides are congruent (AB = DC).Opposite angels are congruent (D = B).Consecutive angles are supplementary (A + D = 180°).If one angle is right, then all angles are right.The diagonals of a parallelogram bisect each other.Each diagonal of a parallelogram separates it into two congruentAlgorithmAccept number of rows and columns from user. Store it in rows and cols variables.To iterate though rows, run an outer loop with the loop structure should look like for(r=1; r

Program DescriptionA sine wave or sinusoid is a mathematical curve that describes a smooth periodic oscillation. A sine wave is a continuous wave. It is named after the function sine, of which it is the graph. It occurs often in pure and applied mathematics, as well as physics,  engineering,  signal processing and many other fields.Print the Mirror Image of Sine-Wave Pattern based on the Wave Height and Wave LengthAlgorithmAccept the Wave Height and Wave LengthPrint the Wave Sign for the Wave Height and the Wave Length.Example/* Program to print the mirror image of Sine Wave*/ #include int main(){    int wave_height;    int wave_length;    int i, j, k;    clrscr(); /*Clears the ...

Program DescriptionPrint the elements of the squared matrix in Z formA square matrix is a matrix with the same number of rows and columns. An n-by-n matrix is known as a square matrix of order AlgorithmTo print the elements of the Square Matrix in Z form We need to print the first row of matrix then diagonal and then last row of the square matrix.Example/* Program to print a square matrix in Z form */ #include int main(){    int rows, cols, r, c, matrix[10][10];    clrscr(); /*Clears the Screen*/    printf("Please enter the number of rows for the Square matrix: ...

JavaFX Button class provides the setOnAction() method that can be used to set an action for the button click event. An EventHandler is a functional interface and holds only one method is the handle() method.Syntax@FunctionalInterface public interface EventHandler extends EventListenerIn the below example, we can able to implement event handling of JavaFX by using a lambda expression.Exampleimport javafx.application.*; import javafx.beans.property.*; import javafx.event.*; import javafx.scene.*; import javafx.scene.control.*; import javafx.scene.layout.*; import javafx.stage.*; public class LambdaWithJavaFxTest extends Application {    public static void main(String[] args) {       Application.launch(args);    }    @Override    public void start(Stage stage) throws Exception {     ...

The DoubleFunction is a built-in functional interface defined in java.util.function package. This interface accepts one double-valued parameter as input and returns a value of type R. As this is a functional interface, it can be used as an assignment target for a lambda expression or method reference. DoubleFunction interface having only one abstract method, apply().Syntax@FunctionalInterface public interface DoubleFunction {  R apply(double value); }Exampleimport java.util.function.DoubleFunction; public class DoubleFunctionTest {    public static void main(String[] args) {       DoubleFunction getGrade = marks -> { // lambda expression          if(marks > 90 && marks 70 && marks 50 && marks
