Algorithm

In C#, operators are symbols or keywords that perform operations on variables and values. C# supports a variety of operators, which can be categorized into several groups:

  1. Arithmetic Operators:
    • + (addition)
    • - (subtraction)
    • * (multiplication)
    • / (division)
    • % (modulus)

Example:

csharp
int a = 10; int b = 3; int result = a + b; // result = 13 
 
  1. Comparison Operators:
    • == (equality)
    • != (inequality)
    • < (less than)
    • > (greater than)
    • <= (less than or equal to)
    • >= (greater than or equal to)

Example:

csharp
int x = 5; int y = 8; bool isEqual = (x == y); // isEqual = false 
 
  1. Logical Operators:
    • && (logical AND)
    • || (logical OR)
    • ! (logical NOT)

Example:

csharp
bool condition1 = true; bool condition2 = false; bool result = condition1 && condition2; // result = false 
 
  1. Assignment Operators:
    • = (assignment)
    • += (add and assign)
    • -= (subtract and assign)
    • *= (multiply and assign)
    • /= (divide and assign)
    • %= (modulus and assign)

Example:

csharp
int num = 10; num += 5; // num is now 15 
 
  1. Increment and Decrement Operators:
    • ++ (increment by 1)
    • -- (decrement by 1)

Example:

csharp
int count = 5; count++; // count is now 6 
 
  1. Bitwise Operators:
    • & (bitwise AND)
    • | (bitwise OR)
    • ^ (bitwise XOR)
    • ~ (bitwise NOT)
    • << (left shift)
    • >> (right shift)

Example:

csharp
int num1 = 5; // binary: 0101 int num2 = 3; // binary: 0011 int result = num1 & num2; // result = 1 (binary: 0001) 
 

These are some of the fundamental operators in C#. They play a crucial role in performing various operations on variables and values in your programs.

 

Code Examples

#1 Basic Assignment Operator in C# Program

Code - C# Programming

using System;

namespace Operator
{
	class AssignmentOperator
	{
		public static void Main(string[] args)
		{
			int firstNumber, secondNumber;
			// Assigning a constant to variable
			firstNumber = 10;
			Console.WriteLine("First Number = {0}", firstNumber);

			// Assigning a variable to another variable
			secondNumber = firstNumber;
			Console.WriteLine("Second Number = {0}", secondNumber);
		}
	}
