Chapter 2: Problem 1

How many operands does each of the following types of operators require? _______ Unary _______ Binary _______ Ternary

Short Answer

Expert verified
Answer: Unary operators require one operand, binary operators require two operands, and ternary operators require three operands.

Step by step solution

01

Unary Operators

Unary operators require only one operand to perform their operation. Common examples of unary operators include negation (-), not (!), or the increment/decrement operators (++, --). For example, if we have a variable x, we can apply the negation operator like this: -x.
02

Binary Operators

Binary operators require two operands to perform their action. These are the most common operators in mathematics and programming languages. Examples of binary operators include addition (+), subtraction (-), multiplication (*), and division (/). For instance, if we have two variables x and y, we can apply the addition operator like this: x + y.
03

Ternary Operators

Ternary operators require three operands to perform their action. There is only one common ternary operator in programming languages, which is the conditional operator (?:). This operator is used as a shorthand for if-then-else statements. The syntax for the operator is: (condition) ? value_if_true : value_if_false. For example, if we have three variables x, y, and z, we can use the ternary operator to assign the minimum value of x and y to z like this: z = (x < y) ? x : y.
