Conditional (Ternary) Operator (?:)

condition ? first_expression : second_expression;

int input = Convert.ToInt32(Console.ReadLine());
string classify;

// if-else construction.
if (input > 0)
    classify = "positive";
else
    classify = "negative";

// ?: conditional operator.
classify = (input > 0) ? "positive" : "negative";

?? operator is called the null-coalescing operator.
The null-coalescing operator (??) is used to define a default value for a nullable type. It returns the left-hand operand if it is not null; otherwise it returns the right operand. When we work with databases, we often deal with absent values. These values come as nulls to the program. This operator is a convenient way to deal with such situations.
