Hence, the result of the conditional operator is the result of evaluation of the expression considered for evaluation. For an expression stated as x? Otherwise, operand b will be evaluated. This term is also known as ternary operator or inline if iif. A conditional operator is the only ternary operator taking three operands in C. It forms as an alternative to the if-else construct, which provides better conciseness with less code and better readability.

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:.

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:.
