C# switch case statement example: Here, we are going to design a simple calculator using switch case statement in C#.
Example: Simple Calculator using switch Statement import java.util.* fun main(args: Array<String>) { val reader = Scanner(System.`in`) print("Enter two numbers: ") // nextDouble() reads the next double from the keyboard val first = reader.nextDouble() val second = reader.nextDouble() ...
In this program, we will create a simple calculator to perform addition, subtraction, multiplication, and division operations using a switch case. Program/Source Code: The source code tocreate a simple calculator using the switch caseis given below. The given program is compiled and executed succe...

Then, switch...case statement is used for checking the operator entered by user. If user enters + then, statements for case: '+' is executed and program is terminated. If user enters - then, statements for case: '-' is executed and program is terminated. This program works similarly for...
It can be very cumbersome, error prone, and time consuming to converse with a computer using only zeros and ones. Numerical machine code (computer code using only zeros and ones) does exist but is rarely used by programmers. For that reason most people program using a “higher-level” ...
switch(choice) { case1: parkCar(); break; case2: removeCar(); break; case3: viewParkedCars(); break; case4: System.exit(0); default: System.out.println("Invalid choice. Please try again."); } } } Define a public static method,parkCar(),with no return type. If there are no ...
The Java Object Mapper is a simple, light-weight framework used to map POJOs to the Aerospike database. Using simple annotations or a configuration YAML file to describe how to map the data to Aerospike, the project takes the tedium out of mapping the da
