The conditional operator? The conditional operator works as follows:. The first operand is implicitly converted to bool. It is evaluated and all side effects are completed before continuing. If the first operand evaluates to true 1 , the second operand is evaluated. If the first operand evaluates to false 0 , the third operand is evaluated.
The result of the conditional operator is the result of whichever operand is evaluated — the second or the third. Only one of the last two operands is evaluated in a conditional expression. Conditional expressions have right-to-left associativity. The first operand must be of integral or pointer type.
The following rules apply to the second and third operands:. If both operands are of arithmetic or enumeration types, the usual arithmetic conversions covered in Standard Conversions are performed to convert them to a common type. If both operands are of pointer types or if one is a pointer type and the other is a constant expression that evaluates to 0, pointer conversions are performed to convert them to a common type.
If both operands are of reference types, reference conversions are performed to convert them to a common type. If the operands have different types and at least one of the operands has user-defined type then the language rules are used to determine the common type. During compilation, the C compiler translates the ternary expression into branch statements, which can condense multiple if statements and reduce nesting at the level of source code.
Sometimes, the code generated for a ternary operator can boost performance by reordering some of the instructions. Properties of a conditional operator are:. By: Ariella Brown Contributor.

What Does Conditional Operator Mean? Techopedia Explains Conditional Operator A conditional operator is the only ternary operator taking three operands in C. Properties of a conditional operator are: It is right-associative, implying that operations are grouped form right to left. It always evaluates one of the two expressions specified after the conditional operator symbol.
It never evaluates both.
Enter the number of items: then perform this task else. Program description:- Find largest among syntax of the conditional operator. The second argument is the in Resume writer text The conditional operator and the third argument is the result of a false. Since the conditional operator in result of a true comparison, therefore it is also called a ternary operator. If the condition is true if-else statement. If you enjoyed this post.

The conditional statements are the decision-making statements which depends upon the output of the. The conditional operator is kind of similar to the if-else statement as it does follow the same algorithm as of if-else statement but the. Conditional Operator Example.
