Java Program to Check if two of three Boolean variables are true
In this article, we will learn to check if any two out of three boolean values are true or not. Boolean variables are datatypes that contain only true or false values. Below is a demonstration of the same - Input: true, true, falseOutput : Two of the three variables are true Checking if two of three Boolean variables are trueIn this article, we will discuss two approaches to check it, and they are - Using if-else Condition ...
Read MoreWhat are C++ Floating-Point Constants?
Floating-point constants specify values that must have a fractional part.Floating-point constants have a "mantissa, " which specifies the value of the number, an "exponent, " which specifies the magnitude of the number, and an optional suffix that specifies the constant's type(double or float).The mantissa is specified as a sequence of digits followed by a period, followed by an optional sequence of digits representing the fractional part of the number. For example −24.25 12.00These values can also contain exponents. For example, 24.25e3 which is equivalent to 24250In C++ you can use the following code to create a floating point constant −Example#include ...

In this article, we will understand how to print inverted 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 size : 8OutputThe desired output would be −The inverted star pattern *************** ************* *********** ********* ******* ***** *** *AlgorithmStep 1 - START Step 2 - Declare four integer values namely i, j, k and my_input. Step 3 ...
Read MoreJava Program to Round a Number to n Decimal Places
In this article, we will understand how to round a number to n decimal places. Rounding of decimal values are done using the CEIL or FLOOR functions.Below is a demonstration of the same −InputSuppose our input is −Input : 3.1415OutputThe desired output would be −Output : 3.2 AlgorithmStep 1 - START Step 2 - Declare a float variable values namely my_input. Step 3 - Read the required values from the user/ define the values Step 4 – Use the CEIL function to round the number to the required decimal places. In this example we are rounding up to 2 decimal ...
Read MoreJava Program to Print Hollow Right Triangle Star Pattern
In this article, we will understand how to print hollow right triangle star pattern. The pattern is formed by using multiple for-loops and print statements. For the pyramid at the first line it will print one star, and at the last line it will print n number of stars. For other lines it will print exactly two stars at the start and end of the line, and there will be some blank spaces between these two starts.Below is a demonstration of the same −InputSuppose our input is −Enter the size : 8OutputThe desired output would be −The hollow pyramid triangle ...
Read MoreJava Program to Generate Multiplication Table
In this article, we will understand how to print a multiplication table. Multiplication table is created by iterating the required input 10 times using a for loop and multiplying the input value with numbers from 1 to 10 in each iteration.Below is a demonstration of the same −InputSuppose our input is −Input : 16OutputThe desired output would be −The multiplication table of 16 is : 16 * 1 = 16 16 * 2 = 32 16 * 3 = 48 16 * 4 = 64 16 * 5 = 80 16 * 6 = 96 16 * 7 = 112 ...

To import any package in the current class you need to use the import keyword asimport packagename;Exampleimport java.lang.String; public class Sample { public static void main(String args[]) { String s = new String("Hello"); System.out.println(s); } }OutputHello
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 ...
