which of the following is defined as a collection of values variable and operators
identifier
float
expression
operator
Expression
The correct answer is expression. An expression is defined as a collection of values, variables, and operators that can be evaluated to produce a single value. It can include things like arithmetic operations, logical operations, and more.
The option that is defined as a collection of values, variables, and operators is called an expression.
To understand this, let's break it down:
1. Identifier: An identifier is a name given to a variable, function, or any other user-defined item in a program. It is used to refer to that item in the code.
2. Float: Float is a data type in programming that is used to represent decimal numbers.
3. Expression: An expression is a combination of values, variables, and operators that produce a result when evaluated. It can include literals (specific values), variables, and operations such as addition, subtraction, multiplication, division, etc.
4. Operator: An operator is a symbol that represents a specific operation to be performed on one or more operands (values or variables). For example, + is an addition operator, - is a subtraction operator, * is a multiplication operator, / is a division operator, etc.
Therefore, the correct answer is "expression" as it encompasses the collection of values, variables, and operators working together to produce a result.
