A ternary operator is an operator that requires three operands, as opposed to a binary operator that requires two operands and a unary operator that requires just one operand.
C++ has just one ternary operator, the conditional ternary operator:
<boolean expression> ? <expression #1> : <expression #2>;
If the boolean expression evaluates true, the first expression is evaluated, otherwise the second expression is evaluated.
A typical usage of this operator is to return the larger (or smaller) of two values of type T:
template<typename T>
T max (T a, T b) {return a<b ? b : a};
template<typename T>
T min (T a, T b) {return a<b ? a : b};
These are really nothing more than notational shorthand for the following:
template<typename T>
T max (T a, T b) {if (a<b) return b; else return a; };
template<typename T>
T min (T a, T b) {if (a<b) return a; else return b;};
However, because ternary expressions are evaluated, the return value of the expression can be used in more complex expressions:
int a=42, b=0;
// ...
int c = ((a>b ? a : b) = 1);
In the above expression, whichever is the larger of a and b will be assigned the value 1 which will also be assigned to c. Thus a and c become 1 while b remains 0.
The conditional operator is also known as ternary operator. It is called ternary operator because it takes three arguments. The conditional operator evaluates an expression returning a value if that expression is true and different one if the expression is evaluated as false.Syntax:condition ? result1 : result2If the condition is true, result1 is returned else result2 is returned.
Compare the first two numbers with the ternary operator. Store the result in a temporary variable. Compare the temporary variable with the third number, again using the ternary operator.
The only "special" operators in C++ are those that cannot be overloaded. That is; the dot member operator (.), pointer to member operator (.*), ternary conditional operator (:?), scope resolution operator (::), sizeof() and typeof().

A ternary operator takes 3 operands. The only one I can think of in C# or C is the"? :" operator: ? : For example:Console.Write(1==2 ? "Huh?" : "Impossible"); //Impossible is printed

The ternary operator, used in C and adapted into many other programming languages, such as Java, provides a convenient shortcut for an "if" loop in many cases. Consider this example. if (age >= 18) result = "old enough"; else result = "too young"; This can be written as: result = (age >= 18) ? "old enough" : "too young"; For this to work, the same action must be performed in the "if" and in the "else". In this example, assign the result to the same variable. This is because the ternary operator just calculates a single result based on a condition.

&& and are short circuit operator in C. It means that expressions chained with these operators are only evaluated until the result is unambiguously determined. For example, the expression a && b is guaranteed to be false if a is false. In this case, the term b is not evaluated, and any possible side-effects of b will not occur. The logical OR () is implemented in a similar fashion: c d is guaranteed to be true of c evaluates to true, and d is not being evaluated in this case. The ternary ? operator is not a short circuit operator (this was listed as a short-circuit operator in a previous revision of this answer). An expression that uses the ternary operator, for example e = f ? g : h is nothing but an alternative form of an if-else construct. The terms f, g and h may each contain short-circuit operators and be evaluated in the manner discussed above, but the ternary operator itself has no short-circuit characteristic.
