How to convert to golang

Golang (also known as Go) is an open source, efficient, and concurrent programming language. With the advent of the era of cloud computing and big data, Golang has gradually become popular in fields such as high concurrency and large-scale distributed systems. Whether you want to improve your programming skills or further develop your career, turning to Golang is a good choice. This article will introduce some basic knowledge, learning resources and practical experience of Golang to readers to help readers make a better transition to Golang.

1. Basic knowledge of Golang

1. Constants and variables

Golang supports constants and variables. Constants refer to values ​​that do not change while the program is running, while variables can be assigned and modified while the program is running. To declare a variable, you can use the var keyword, for example:

var age int
age = 29

To declare a constant, you can use the const keyword, for example:

const pi float32 = 3.1415926

2. Data type

Golang There are many data types, such as integer, floating point, Boolean, string, etc. Among them, integer types can be divided into different types such as int, int8, int16, int32, int64, etc., while floating point types can be divided into different types such as float32, float64, etc. The Boolean type has only two values, true and false. A string is a sequence of characters enclosed in double or single quotes.

3. Function

A function in Golang starts with the keyword func and contains a function name, parameters and return value. For example:

func Add(a int, b int) int {
    return a + b
}

4. Loops and conditional statements

Loops and conditional statements in Golang are similar to other programming languages. The if statement is used to determine whether the condition is true, and the for statement is used to execute the code block in a loop. For example:

if age >= 18 {
    fmt.Println("成年人")
} else {
    fmt.Println("未成年人")
}
