C# Operator Example

In this chapter you will learn:

• The main objective of this chapter is to explain you in details about how to use C# operators in a program.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace operator_example_1
{
    class Program
    {
        static void Main(string[] args)
        {
            char ch;

            Console.Write("Enter a character: \t");
            ch = Convert.ToChar(Console.ReadLine());

            if (ch == 'a' || ch == 'A' || ch == 'e' || ch == 'E' || ch == 'i' || ch == 'I' || ch == 'o' || ch == 'O' || ch == 'u' || ch == 'U')
            {
                Console.WriteLine("\n\n{0} is vowel", ch);
            }
            else
            {
                Console.WriteLine("\n\n{0} is not vowel", ch);
            }
            Console.ReadLine();
        }
    }
}

Enter a character :     E



E is vowel

namespace operator_example_2
{
    class Program
    {
        static void Main(string[] args)
        {
            int height, width, area;

            Console.Write("Enter height:\t");
            height = Convert.ToInt32(Console.ReadLine());

            Console.Write("Enter width:\t");
            width = Convert.ToInt32(Console.ReadLine());

            area = height * width;

            Console.WriteLine("\nArea of Rectangle is {0}", area);
            Console.ReadLine();
        }
    }
}

Enter height :   5

Enter width :    6

Area of Rectangle is 30
