Question

Which of the following stores only one type of data and In a specific location and must contain some value, meaning it cannot be null

Float
Expression
Primitive data structure
Operator

Answer 1

Primitive data structure

Answer 2

The option that best fits the description of a store that only accepts one type of data, is located in a specific location, and must contain some value, meaning it cannot be null, is a primitive data structure.

Answer 3

The data structure that fits the given description is a primitive data structure.

A primitive data structure is a basic data type that stores a single value in a specific location and must have a value, meaning it cannot be null. Examples of primitive data types include integers, floating-point numbers, characters, and booleans.

To determine the answer to this question, we can look at the characteristics of the given options:

1. Float: A float is a primitive data type that represents a floating-point number (decimal number). It does store one type of data (floating-point numbers), but it can be null (if it is declared with the nullable type). Therefore, it does not fit the description given.

2. Expression: An expression is a combination of variables, operators, and functions that results in a single value. It does not store data itself but rather represents a computation or evaluation. Hence, it does not fit the description.

3. Primitive data structure: As explained earlier, primitive data structures store a single value in a specific location and must have a value. They can only hold one type of data, and examples include integers, floating-point numbers, characters, and booleans. Therefore, this option fits the given description.

4. Operator: An operator is a symbol or a function that performs an operation on one or more operands. It does not store data itself but rather manipulates or performs operations on data. Therefore, it does not fit the description.

So, the correct answer is "Primitive data structure" as it only stores one type of data, in a specific location, and must contain a value (cannot be null).
