To determine the ordering of data types from largest to smallest data storage, we need to consider the typical capacity and size of each data type. Here are the general characteristics of the data types provided:
1. String: A String can store an arbitrary number of characters. It is generally considered the largest because its size can grow dynamically based on the content stored.
2. double: A double is a data type that stores decimal numbers and usually occupies 8 bytes (64 bits) of memory.
3. int: An int typically stores whole numbers and occupies 4 bytes (32 bits) of memory.
4. boolean: A boolean represents a truth value (true or false) and is usually represented by 1 bit, although it often occupies 1 byte in memory for simplicity.
Now, let's analyze the provided answer choices:
1. int, double, boolean, String:
- int (32 bits)
- double (64 bits)
- boolean (1 bit or 1 byte)
- String (variable length, usually the largest)
2. All the data types are the same size:
- This is incorrect because the data types have different sizes.
3. int, String, double, boolean:
- int (32 bits)
- String (variable length, usually largest)
- double (64 bits)
- boolean (1 bit or 1 byte)
4. String, double, int, boolean:
- String (variable length, usually largest)
- double (64 bits)
- int (32 bits)
- boolean (1 bit or 1 byte)
5. double, string, boolean, int:
- double (64 bits)
- string (variable length, usually largest)
- boolean (1 bit or 1 byte)
- int (32 bits)
Given all these options, the correct sequence from the largest to the smallest data type is String, double, int, boolean. This means that the third option is correct:
String, double, int, boolean
Therefore, the correct answer is:
3
