assignment operators

Assignment Operators 

There are following assignment operators supported by C#: 

=           Simple assignment operator, Assigns values from right side operands to left side operand
             C = A + B assigns value of A + B into C
+=       Add AND assignment operator, It adds right operand to the left operand and assign the result               to left operand   C += A is equivalent to C = C + A
-=       Subtract AND assignment operator, It subtracts right operand from the left operand and assign            the result to left operand  C -= A is equivalent to C = C – A
*=      Multiply AND assignment operator, It multiplies right operand with the left operand and assign            the result to left operand  C *= A is equivalent to C = C * A
/=        Divide AND assignment operator, It divides left operand with the right operand and assign the            result to left operand  C /= A is equivalent to C = C / A
%=      Modulus AND assignment operator, It takes modulus using two operands and assign the                       result to left operand  C %= A is equivalent to C = C % A
<<=     Left shift AND assignment operator C <<= 2 is same as C = C << 2
>>=   Right shift AND assignment operator C >>= 2 is same as C = C >> 2
&=     Bitwise AND assignment operator C &= 2 is same as C = C & 2
^=      bitwise exclusive OR and assignment operator C ^= 2 is same as C = C ^ 2
|=      bitwise inclusive OR and assignment operator C |= 2 is same as C = C | 2

Example 

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

using System;
namespace OperatorsAppl
{
    class Program
    {
        static void Main(string[] args)
        {
            int a = 21;
            int c;
            c = a;
            Console.WriteLine("Line 1 - =  Value of c = {0}", c);
            c += a;
            Console.WriteLine("Line 2 - += Value of c = {0}", c);
            c -= a;
            Console.WriteLine("Line 3 - -=  Value of c = {0}", c);
            c *= a;
            Console.WriteLine("Line 4 - *=  Value of c = {0}", c);

            c /= a; 

            Console.WriteLine("Line 5 - /=  Value of c = {0}", c);  

            c = 200; 

            c %= a; 

            Console.WriteLine("Line 6 - %=  Value of c = {0}", c);  

            c <<= 2; 

            Console.WriteLine("Line 7 - <<=  Value of c = {0}", c);  

            c >>= 2; 

            Console.WriteLine("Line 8 - >>=  Value of c = {0}", c);  

            c &= 2; 

            Console.WriteLine("Line 9 - &=  Value of c = {0}", c);  

            c ^= 2; 

            Console.WriteLine("Line 10 - ^=  Value of c = {0}", c);  

            c |= 2; 

            Console.WriteLine("Line 11 - |=  Value of c = {0}", c); 

            Console.ReadLine(); 

        } 

    }
