What are the characteristics of data types in go language?

Data type features include static typing, strong typing, memory safety, support for pointers, rich data types, support for custom types, concurrency safety, etc. Detailed introduction: 1. Static typing: Go language is a statically typed language. Variables must specify types when they are declared, and their types cannot be changed at will; 2. Strong typing: Go language is a strongly typed language and does not allow implicit types between different types. Type conversion requires explicit type conversion; 3. Memory safety: The data type design of Go language takes memory safety into consideration and avoids common memory errors, such as out-of-bounds access, null pointer reference, etc.

The data types of Go language have the following characteristics:

1. Static type: Go language is a static type language. Variables must specify their type when they are declared, and they cannot be changed at will. type.

2. Strong type: Go language is a strongly typed language, which does not allow implicit conversion between different types and requires explicit type conversion.

3. Memory safety: The data type design of Go language takes memory safety into consideration and avoids common memory errors, such as out-of-bounds access, null pointer reference, etc.

4. Support pointers: Go language supports pointer types, but compared to languages such as C/C, the use of pointers is restricted, avoiding some common pointer errors.

5. Rich data types: Go language provides rich data types, including basic data types and composite data types, which can meet various needs.

6. Support custom types: Go language supports custom types. You can define new types through the type keyword to improve the readability and maintainability of the code.

7. Concurrency safety: The data type design of Go language takes concurrency safety into consideration, supports concurrent programming, and avoids some common concurrency problems.
