In programming, the ternary operator is mostly defined with what symbol(s)?

The ternary operator in programming, also known as the conditional operator, is mostly defined with the symbols "?:" because these symbols represent the structure of the operator. The "?" symbol is used to separate the condition that is being tested, while the ":" symbol separates the two possible outcomes based on the condition. This concise syntax allows for writing conditional expressions more compactly and makes the code more readable and concise.
