ternary conditional operator что это
Conditional Operator in C is a powerful Operator which can be used to implement if-then-else type of logic. This operator is also known as ternary operator as it takes three expressions in following form. ConditionalExpression ? Возвражает одно из двух выражений в зависимости от условия. expression1, expression2. test. Любое логическое выражение. expression1. Выражение, возвращаемое, если значение test равно true. Может быть выражением с запятой. expression2. The ternary operator is a syntactic and readability convenience, not a performance shortcut. People are split on the merits of it for conditionals of varying complexity, but for short conditions, it can be useful to have a one-line expression. The conditional operator (also called the ternary operator) evaluates a boolean expression and returns one of two values depending on the result. You use the ternary conditional operator to evaluate a question and then do one of two things based on the result of the question. The ternary conditional operator is written like this: question ? action1 : action2 (see Listing 16-1).

If they are not, but are both arithmetic data types, the usual arithmetic conversions are applied to make their types the same. It is also called ternary operators. Example Program For Conditional or Ternary operator. Every self-respecting C/C programmer knows what the ternary operator is, and most everyone used it at least once in their programs.
