In c#, Relational Operators are useful to check the relation between two operands like we can determine whether two operand values equal or not, etc. based on our requirements.
Generally, in c# the relational operators will return true only when the defined operands relationship becomes true otherwise, it will return false.
For example, we have integer variables a = 10, b = 20 and if we apply a relational operator >= (a >= b), we will get the result false because the variable “a” contains a value which is less than variable b.
The following table lists the different types of operators available in c# relational operators.
| Operator | Name | Description | Example (a = 6, b = 3) |
|---|---|---|---|
| == | Equal to | It compares two operands and it returns true if both are the same. | a == b (false) |
| > | Greater than | It compares whether left operand greater than the right operand or not and returns true if it is satisfied. | a > b (true) |
| < | Less than | It compare whether left operand less than right operand or not and return true if it is satisfied. | a < b (false) |
| >= | Greater than or Equal to | It compares whether left operand greater than or equal to right operand or not and return true if it is satisfied. | a >= b (true) |
| <= | Less than or Equal to | It compares whether left operand less than or equal to right operand or not and return true if it is satisfied. | a <= b (false) |
| != | Not Equal to | It checks whether two operand values equal or not and return true if values are not equal. | a != b (true) |
Following is the example of using the Relational Operators in c# programming language.
using System;
namespace Tutlane
{
class Program
{
static void Main(string[] args)
{
bool result;
int x = 10, y = 20;
result = (x == y);
Console.WriteLine("Equal to Operator: " + result);
result = (x > y);
Console.WriteLine("Greater than Operator: " + result);
result = (x <= y);
Console.WriteLine("Lesser than or Equal to: "+ result);
result = (x != y);
Console.WriteLine("Not Equal to Operator: " + result);
Console.WriteLine("Press Enter Key to Exit..");
Console.ReadLine();
}
}
}
If you observe the above code, we used different Relational operators (<, >, ==) to perform required operations on defined operands.
When we execute the above c# program, we will get the result like as shown below.
This is how we can use the relational operators in c# programming language to check the relationship between defined operands based on our requirements.
