Assignment operators.

	=   +=   -=   *=   /=   %=   <<= >>=   &=   ^=   |=

= is the obvious one. It takes the result of the expression on the right and assigns it to the variable on the left (lvalue).

	main ()
        {
	  int a, b=4, c=10;
	  a = b + c;
	}

I know this is stating the obvious, but:

1. b is assigned the value 4
2. c is assigned the value 10
3. a is assigned the result of b plus C (14).

	main ()				main()
	{				{
	  int a=4;			  int a=4;
	  a = a * 4;			  a *= 4;
	}				}

The rule is as follows:

The lvalue is multiplied by the rvalue and the result assigned to the lvalue.

Here is another example.

	main()				main()
	{				{
	    int a=10, b=2;	            int a=10, b=2;
	    a /= b * 5;		            a = a / (b*5);
	}				}

Again both preduce the same answer (1).
