C# Tutorial P5 - Common Operators

[Admin]

Assignment Operator =
Arithmetic Operators like +,-,*,/,%
Comparison Operators like ==, !=,>, >=, <, <=
Conditional Operators like &&, ||
&& means "and". || means "or"
Ternary Operator ?:
Null Coalescing Operator ??

Sample Code:

using System;

class Program
{
    static void Main()
    {
        int Numerator = 10;
        int Denominator = 2;
        
        int Result = Numerator / Denominator;

        Console.WriteLine("Result = {0}", Result);
    }
}

using System;

class Program
{
    static void Main()
    {
        int Number = 10;
        int AnotherNumber = 20;
        
        // Number is not equal 10
        if (Number != 10 && AnotherNumber == 20)
        {
            Console.WriteLine("Hello");
        }
    }
}

Program without ternary Operator

using System;

class Program
{
    static void Main()
    {
        int Number = 10;

        bool IsNumber10;

        if (Number == 10)
        {
            IsNumber10 = true;
        }
        else
        {
            IsNumber10 = false;                
        }

        Console.WriteLine("Number == 10 is {0}", IsNumber10);
    }
}

Same program with ternary Operator

using System;
class Program
{
    static void Main()
    {
        int Number = 10;

        bool IsNumber10 = Number == 10 ? true : false;

        Console.WriteLine("i == 10 is {0}", IsNumber10);
    }
}
