Relational operators are used to check the relationship between two operands. If the relationship is true the result will be true, otherwise it will result in false.
Relational operators are used in decision making and loops.
| Operator | Operator Name | Example |
|---|---|---|
| == | Equal to | 6 == 4 evaluates to false |
| > | Greater than | 3 > -1 evaluates to true |
| < | Less than | 5 < 3 evaluates to false |
| >= | Greater than or equal to | 4 >= 4 evaluates to true |
| <= | Less than or equal to | 5 <= 3 evaluates to false |
| != | Not equal to | 10 != 2 evaluates to true |
Example: Relational Operators
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 | using System; namespace Operator { class RelationalOperator { public static void Main(string[] args) { bool result; int firstNumber = 10, secondNumber = 20; result = (firstNumber==secondNumber); Console.WriteLine("{0} == {1} returns {2}",firstNumber, secondNumber, result); result = (firstNumber > secondNumber); Console.WriteLine("{0} > {1} returns {2}",firstNumber, secondNumber, result); result = (firstNumber < secondNumber); Console.WriteLine("{0} < {1} returns {2}",firstNumber, secondNumber, result); result = (firstNumber >= secondNumber); Console.WriteLine("{0} >= {1} returns {2}",firstNumber, secondNumber, result); result = (firstNumber <= secondNumber); Console.WriteLine("{0} <= {1} returns {2}",firstNumber, secondNumber, result); result = (firstNumber != secondNumber); Console.WriteLine("{0} != {1} returns {2}",firstNumber, secondNumber, result); } } } |
