CSharp - Write program to Do Calculation with Compound Assignments

Requirements

You will write a program that uses compound assignment in connection with adding, subtraction, multiplication, and division.

  • Read user input
  • Store the user input into a variable
  • Use the Compound Assignments:+= -+ /= *=

Hint

The program works with the same variable every time!

The division here is integer division since both number and 2 are ints.

Demo

using System;
class Program/* w ww  .  ja  v a2s  .  c o  m*/
{
    static void Main(string[] args)
    {
        // Input 
        Console.Write("Enter a number: ");
        string input = Console.ReadLine();
        int number = Convert.ToInt32(input);

        // Calculation using compound assignment  
        number += 10; // same as number = number + 10; 

        // Result output 
        Console.WriteLine("Number ten more greater is: " + number);
        
        // With subtraction 
        number -= 5; // same as number = number - 5; 
        Console.WriteLine("After decrease by 5: " + number);

        // With multiplication 
        number *= 10; // same as number = number * 10; 
        Console.WriteLine("Ten times greater: " + number);

        // With division 
        number /= 2; // same as number = number / 2; 
        Console.WriteLine("Decreased to one half: " + number);
    }
}

Result
