Relational operators are used to compare the values and returns Boolean values, if condition is true – they return True, otherwise they return False.

Here is the list of relation operators,

  1. "==" (Equal To) – it returns true, if both operand’s values are equal
  2. "!=" (Not Equal To) – it returns true, if both operand’s values are not equal
  3. "<" (Less Than) – it returns true if first, operand is less than second operand
  4. "<=" (Less Than or Equal To) – it returns true, if either first operand is less than or equal to second operand
  5. ">" (Greater Than) – it returns true, if first operand is greater than second operand
  6. ">=" (Greater Than or Equal To) – it returns true, if either first operand is greater than or equal to second operand

Syntax:

    Operand1 == Operand2
    Operand1 != Operand2
    Operand1 < Operand2
    Operand1 <= Operand2
    Operand1 > Operand2
    Operand1 >= Operand2

Example:

    Input:
    int a = 10;
    int b = 3;
    
    Console.WriteLine("a==b: {0}", (a == b));
    Console.WriteLine("a!=b: {0}", (a != b));
    Console.WriteLine("a>b : {0}", (a > b));
    Console.WriteLine("a>=b: {0}", (a >= b));
    Console.WriteLine("a<b : {0}", (a < b));
    Console.WriteLine("a<=b: {0}", (a <= b));

    Output:
    a==b: False
    a!=b: True
    a>b : True
    a>=b: True
    a<b : False
    a<=b: False

C# code to demonstrate example of relational operators

            //checking conditions in another way
            if ((a == b) == true)
                Console.WriteLine("a is equal to b");
            else

            else
                Console.WriteLine("a is not less than or equal to b");

            //hit ENTER to exit the program
            Console.ReadLine();
        }
    }

Output

Return type of == operator: System.Boolean
Return type of != operator: System.Boolean
Return type of > operator : System.Boolean
Return type of >= operator: System.Boolean
Return type of < operator : System.Boolean
Return type of <= operator: System.Boolean
a==b: False
a!=b: True
a>b : True
a>=b: True
a<b : False
a<=b: False
a is not equal to b
a is not equal to b
a is greater than b
a is greater than or equal to b
a is not less than b
a is not less than or equal to b
a is not equal to b
a is not equal to b
a is greater than b
a is greater than or equal to b
a is not less than b
a is not less than or equal to b
