C# - Arithmatic Operators


Advertisements


Following table shows all the arithmetic operators supported by C#. Assume variable A holds 10 and variable B holds 20, then:

Operator Description Example
+ Adds two operands A + B = 30
- Subtracts second operand from the first A - B = -10
* Multiplies both operands A * B = 200
/ Divides numerator by de-numerator B / A = 2
% Modulus Operator and remainder of after an integer division B % A = 0
++ Increment operator increases integer value by one A++ = 11
-- Decrement operator decreases integer value by one A-- = 9

Example

The following example demonstrates all the arithmetic operators available in C#:

using System;
namespace OperatorsAppl 
{
   class Program 
   { 
      static void Main(string[] args) 
      { 
         int a = 21;
         int b = 10;
         int c;

         c = a + b;
         Console.WriteLine("Line 1 - Value of c is {0}", c);
         c = a - b;
         Console.WriteLine("Line 2 - Value of c is {0}", c);
         c = a * b;
         Console.WriteLine("Line 3 - Value of c is {0}", c);
         c = a / b;
         Console.WriteLine("Line 4 - Value of c is {0}", c);
         c = a % b;
         Console.WriteLine("Line 5 - Value of c is {0}", c);
         c = a++;
         Console.WriteLine("Line 6 - Value of c is {0}", c);
         c = a--;
         Console.WriteLine("Line 7 - Value of c is {0}", c);
         Console.ReadLine();
      }
   }
}

When the above code is compiled and executed, it produces the following result:

Line 1 - Value of c is 31
Line 2 - Value of c is 11
Line 3 - Value of c is 210
Line 4 - Value of c is 2
Line 5 - Value of c is 1
Line 6 - Value of c is 21
Line 7 - Value of c is 22
