Question

Write a C# program (Integer Math Calculator, the programming requirements are as follows:

When typing in 3+4, 10-5, 12*12, 15/5 from console, the program should give the right answers on screen like 7, 5, 144, 3.

This is what I have so far:

namespace ConsoleApplication3
{
class Program
{
static void Main(string[] args)
{
String input;
do
{
Console.Write("Type int values to calulate or stop to exit: ");
input = Console.ReadLine();
if (input.ToLower() != "stop")
{
char[] delimiters = { '-', '+', ',', '+', '-', '*', '/' };
String[] tokens = input.Split(delimiters);
int Math = 0;
foreach (String token in tokens)
Math += int.Parse(token);
Console.WriteLine("The sum is: " + Math);

}
} while (input.ToLower() != "stop"); // compare strings
}
}
}

I am trying to get the subtraction, multiplicaton, and divison to fit in above to make it work. Please show work. Thanks

i have written full code for a calculator

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

namespace Arithmetic_Operators

{

    class calculator

    {

        static void Main(string[] args)

        {

            int num1, num2;

            int add, sub, mul;

            float div;

            //get values from users

            Console.Write("Enter number 1\t\t");

            num1 = Convert.ToInt32(Console.ReadLine());

            Console.Write("\n\nEnter number2\t\t");

            num2 = Convert.ToInt32(Console.ReadLine());

  

            //adding values

            add = num1 + num2;

            // subtracting values

            sub = num1 - num2;

            //multiplying values

            mul = num1 * num2;

            //r dividing values

            div = (float)num1 / num2;

            //print Output

            Console.WriteLine("\n\n=====================\n");

            Console.WriteLine("Addition\t\t{0}", add);

            Console.WriteLine("Subtraction\t\t{0}", sub);

            Console.WriteLine("Multiplication\t\t{0}", mul);

            Console.WriteLine("Division\t\t{0}", div);

            Console.WriteLine("\n=======================\n");

            Console.ReadLine();

        }

    }
