Understand in-depth knowledge of commonly used operators in Go language

In-depth understanding of common operators in Go language requires specific code examples

In Go language, operators are symbols used to perform various calculations and operations. . Mastering the use of common operators is very important for writing efficient and correct code. This article will take an in-depth look at common operators in the Go language and demonstrate their usage through specific code examples.

1. Arithmetic operators
   The arithmetic operators in Go language include addition operator ( ), subtraction operator (-), multiplication operator (*), division operator (/) and Remainder operator (%). Here are some sample codes:

package main

import "fmt"

func main() {
    a := 10
    b := 3

    // 加法运算
    c := a + b
    fmt.Println("加法运算结果：", c)

    // 减法运算
    d := a - b
    fmt.Println("减法运算结果：", d)

    // 乘法运算
    e := a * b
    fmt.Println("乘法运算结果：", e)

    // 除法运算
    f := a / b
    fmt.Println("除法运算结果：", f)

    // 取余运算
    g := a % b
    fmt.Println("取余运算结果：", g)
}

2. Comparison operators
   Comparison operators are used to compare the size of two values ​​or determine whether two values ​​are equal. Comparison operators in Go language include equal operator (==), not equal operator (!=), greater than operator (>), less than operator (<), greater than or equal operator (>=) and the less than or equal operator (<=). Here is some sample code:

package main

import "fmt"

func main() {
    a := 10
    b := 5

    // 等于运算
    if a == b {
        fmt.Println("a 等于 b")
    } else {
        fmt.Println("a 不等于 b")
    }

    // 不等于运算
    if a != b {
        fmt.Println("a 不等于 b")
    } else {
        fmt.Println("a 等于 b")
    }

    // 大于运算
    if a > b {
        fmt.Println("a 大于 b")
    } else {
        fmt.Println("a 不大于 b")
    }

    // 小于运算
    if a < b {
        fmt.Println("a 小于 b")
    } else {
        fmt.Println("a 不小于 b")
    }

    // 大于等于运算
    if a >= b {
        fmt.Println("a 大于等于 b")
    } else {
        fmt.Println("a 小于 b")
    }

    // 小于等于运算
    if a <= b {
        fmt.Println("a 小于等于 b")
    } else {
        fmt.Println("a 大于 b")
    }
}

3. Logical operators
   Logical operators are used to perform logical operations based on multiple conditions and return a Boolean value. Logical operators in Go language include logical AND operator (&&), logical OR operator (||) and logical NOT operator (!). Here are some sample codes:

package main

import "fmt"

func main() {
    a := true
    b := false

    // 逻辑与运算
    if a && b {
        fmt.Println("a 和 b 都为真")
    } else {
        fmt.Println("a 和 b 至少有一个为假")
    }

    // 逻辑或运算
    if a || b {
        fmt.Println("a 和 b 至少有一个为真")
    } else {
        fmt.Println("a 和 b 都为假")
    }

    // 逻辑非运算
    if !a {
        fmt.Println("a 为假")
    } else {
        fmt.Println("a 为真")
    }
}

The above are some sample codes for commonly used arithmetic operators, comparison operators and logical operators in Go language. By learning and applying these operators flexibly, you can better master the programming skills of Go language and write more efficient and powerful code. Hope this article is helpful to you!
