Which of the following stores only one type of data in a specific location and must contain some value, meaning it cannot be null?(1 point)
expression
expression
float
float
primitive data structure
primitive data structure
operator
operator
float
float
The correct answer is "primitive data structure."
To arrive at this answer, let's analyze each option:
1. Expression: An expression is a combination of values, variables, and operators that can be evaluated and produces a result. It does not store data itself, so it is not the correct answer.
2. Float: Float is a data type used to represent floating-point numbers. It can store decimal values, but it can also be nullable and contain null values. Therefore, it is not the correct answer.
3. Primitive data structure: Primitive data structures are basic data types built into programming languages. Examples include integers, booleans, characters, and floating-point numbers. These data structures can only store one type of data and must contain some value. They cannot be null. Therefore, this is the correct answer.
4. Operator: An operator is a symbol or function that performs an operation on one or more operands. It is not a data storage mechanism, so it is not the correct answer.
Therefore, the option "primitive data structure" is the only one that meets the given criteria.
