What Is Built Data Structure?


Larry Thompson

A data structure is a way of organizing and storing data in a computer’s memory or disk. It provides a systematic way to access and manipulate the data efficiently. One commonly used type of data structure is a built-in data structure.

What Is a Built Data Structure?

A built-in data structure, also known as a primitive data structure, is a fundamental type of data structure that is provided by the programming language itself. These structures are already defined and implemented in the language, allowing programmers to use them without having to write additional code.

Commonly Used Built Data Structures:

1. Integer

An integer is a whole number without any decimal points.

It can be either positive or negative. In most programming languages, integers have fixed sizes and ranges.

2. Float

A float, short for floating-point number, represents a real number with fractional parts. It can store both whole numbers and decimal values with varying precision.

3. Boolean

A boolean represents one of two possible values: true or false. It is used for logical operations and conditional statements.

4. Character

A character stores a single letter, digit, or special symbol from the character set defined by the programming language.

Advantages of Built-In Data Structures:

  • Simplicity: Built-in data structures are straightforward to use since they come pre-defined in the programming language.
  • Efficiency: These structures are often highly optimized for performance and memory usage, resulting in faster execution times.
  • Portability: Since built-in data structures are part of the language, they are portable and can be used across different platforms and systems.

Disadvantages of Built-In Data Structures:

  • Limitations: Built-in data structures may have limitations in terms of size, range, or functionality. They may not be suitable for complex data manipulation tasks.
  • Lack of Customization: Since these structures are predefined, you cannot modify their behavior or add additional functionality to suit specific requirements.


Built-in data structures are an integral part of programming languages. They provide a foundation for organizing and manipulating data efficiently.

While they offer simplicity and efficiency, they may have limitations in terms of customization and flexibility. It’s essential to understand the characteristics and capabilities of built-in data structures to make informed decisions when designing software solutions.
