     Try this:

     if(new [] {"a", "b", "c"}.Contains(aString)) Console.Out.WriteLine("aString is 'a', 'b' or 'c'");-

     This uses the Contains

     method to search the array for aString.

     Thanks to my Delphi days, I'm also used to its in keyword. For the generic case in C#, I'm using:

     public static class Helper{ public static bool In<T>(this T t, params T[] args) { return args.Contains(t); } }}

     which can be utilized as follows:

     var color = Color.Aqua; var b = color.In(Color.Black, Color.Blue); b = "hello".In("hello", "world");

     No. You can come close:

     if (new [] { "a", "b", "c" }.Contains(aString)) Console.Out.WriteLine("aString is 'a', 'b' or 'c'");

   • += Operator in C++

     While the end result of the e.g. someVar++ operator is the same as someVar += 1 there are other things playing in as well.

     Lets take a simple statement like

     foo = bar++;-

     It's actually equivalent (but not equal) to

     temp = bar;bar += 1;foo = temp;

     As for the prefix and suffix increment or decrement operators, they have different operator precedence, which will affect things like pointer arithmetic using those operators.

     As for the difference between

     foo += 1;-

     and

     foo = foo + 1;-

     there's no different for primitive types (like int or float) or pointer types, but there's a very big difference if foo is an object with operator overloading. Then

     foo += 1;-

     is equal to

     foo.operator+=(1);-

     while

     foo = foo + 1;-

     is equal to

     temp = foo.operator+(1);foo.operator=(temp);-

     Semantically a very big difference. Practically too, especially if any of the operator overload functions have side-effects, or if the copy-constructor or destructor have some side-effects (or you forget the rules of three, five or zero).

     Your commented-out declaration in the header is almost correct. Since it is a friend, it is not a member and thus cannot be const, so it should be:

     friend std::ostream &operator<<(std::ostream &output, const Complex &complexObj);-

     Note also that you need to qualify ostream as std::ostream, since you should not use using namespace std; in a header file (you really shouldn't need to use it anywhere; it's generally better to just write out std:: when you want to use something from the standard library).

     Likewise, in your source file, since it is not a member function, you do not prefix the operator definition with the class name, and it should be:

     std::ostream &operator<<(std::ostream &output, const Complex &complexObj)-

     Just change it to (f < i) which is !(f >= i).

     Note: this is not the case if either f

     or i

     is NaN

     . This is because f >= i

     will evaluate to false

     if either is NaN

     leading to !(f >= i)

     evaluating to true

     where f < i

     evaluates to false

     .

   • The ~ operator in C++ (and other C-like languages like C and Java) performs a bitwise NOT operation - all the 1 bits in the operand are set to 0 and all the 0 bits in the operand are set to 1. In other words, it creates the complement of the original number. For example:
