What are the standard libraries in Go language?
The Go language standard library is a set of toolboxes built into the Go language. It provides a series of libraries and packages that can help us complete various tasks easily. The standard library contains a variety of tools, including string processing, file operations, network programming, encryption, and more. In the Go language, the standard library is very important because it is the core part of the Go language. In this article, we will introduce what the standard libraries are in the Go language and introduce some important standard libraries.
- fmt library
fmt library is one of the most commonly used libraries in the Go language. It provides functions for formatting input and output. The fmt library can output data in various formats to the console or to a file.
- flag library
The flag library is a parameter parsing library in Go language that can easily handle command line parameters. The flag library can receive parameters, options, and identifiers and parse them into corresponding values.
- os library
The os library provides some functions of the operating system, including file operations, environment variable operations, process and signal processing, etc.
- strings library
The strings library is the most important library for operating on strings in the Go language. The strings library provides multiple methods for string splitting, splicing, replacement, and comparison.
- time library
The time library provides functions related to time processing. The time library can obtain the current time, set timers, calculate time differences, etc.
- net/http library
The net/http library provides functions related to the HTTP protocol, making it easy to write Web server and client programs.
- encoding/json library
encoding/json library is a JSON data serialization library in Go language. It provides a series of functions for serializing Go data structures into JSON format and deserializing JSON data into Go data structures.
- crypto library
The crypto library provides a series of encryption-related functions such as encryption, decryption, and hashing. It can use commonly used encryption algorithms such as AES, RSA, SHA, etc.
- sync library
The sync library provides concurrency-related functions. It can implement concurrent operations such as locks, semaphores, and condition variables.
- database/sql library
database/sql library is a SQL database access library in the Go language. It supports various SQL databases such as MySQL, PostgreSQL, etc.
The above are the most commonly used standard libraries in the Go language. Of course, there are many other standard libraries, such as the container library, bufio library, etc.
In short, the standard library in the Go language provides developers with a powerful basic library that can easily carry out various development work. In actual development, you can choose the standard libraries you need to use according to specific needs. These standard libraries can allow us to develop efficient and stable applications faster.

Golang and C each have their own advantages in performance competitions: 1) Golang is suitable for high concurrency and rapid development, and 2) C provides higher performance and fine-grained control. The selection should be based on project requirements and team technology stack.

Golang is suitable for rapid development and concurrent programming, while C is more suitable for projects that require extreme performance and underlying control. 1) Golang's concurrency model simplifies concurrency programming through goroutine and channel. 2) C's template programming provides generic code and performance optimization. 3) Golang's garbage collection is convenient but may affect performance. C's memory management is complex but the control is fine.

C is more suitable for scenarios where direct control of hardware resources and high performance optimization is required, while Golang is more suitable for scenarios where rapid development and high concurrency processing are required. 1.C's advantage lies in its close to hardware characteristics and high optimization capabilities, which are suitable for high-performance needs such as game development. 2.Golang's advantage lies in its concise syntax and natural concurrency support, which is suitable for high concurrency service development.

Golang excels in practical applications and is known for its simplicity, efficiency and concurrency. 1) Concurrent programming is implemented through Goroutines and Channels, 2) Flexible code is written using interfaces and polymorphisms, 3) Simplify network programming with net/http packages, 4) Build efficient concurrent crawlers, 5) Debugging and optimizing through tools and best practices.

The core features of Go include garbage collection, static linking and concurrency support. 1. The concurrency model of Go language realizes efficient concurrent programming through goroutine and channel. 2. Interfaces and polymorphisms are implemented through interface methods, so that different types can be processed in a unified manner. 3. The basic usage demonstrates the efficiency of function definition and call. 4. In advanced usage, slices provide powerful functions of dynamic resizing. 5. Common errors such as race conditions can be detected and resolved through getest-race. 6. Performance optimization Reuse objects through sync.Pool to reduce garbage collection pressure.

Go language performs well in building efficient and scalable systems. Its advantages include: 1. High performance: compiled into machine code, fast running speed; 2. Concurrent programming: simplify multitasking through goroutines and channels; 3. Simplicity: concise syntax, reducing learning and maintenance costs; 4. Cross-platform: supports cross-platform compilation, easy deployment.
