Basic Data Types in C++

C++ provides several fundamental data types that are used to define variables. These data types specify the type and size of data associated with variables.

Key Topics

List of Basic Data Types

  • int - Integer numbers
  • float - Floating-point numbers
  • double - Double-precision floating-point numbers
  • char - Single characters
  • bool - Boolean values (true or false)
  • void - Empty data type

Explanation: These basic data types form the building blocks for variable declaration and manipulation in C++.

Key Takeaways

  • Understanding basic data types is essential for effective programming.
  • Choose the appropriate data type based on the data you need to store.

Size of Data Types

The size of data types may vary based on the compiler and system architecture, but generally:

  • int - Typically 4 bytes
  • float - Typically 4 bytes
  • double - Typically 8 bytes
  • char - 1 byte
  • bool - 1 byte

Explanation: Knowing the size helps in memory management and understanding the range of values a data type can hold.
