Revealing the highest precedence of operators in Go language? Unravel the fog

The highest precedence operators in Go language are multiplication and division operators. They have the same precedence, higher than the addition and subtraction operators.

First, let’s understand the priority of operators in Go language. Operators in the Go language can be divided into the following levels, arranged from high to low priority:

1. Unary operators (such as the address operator & and the negation operator ^)
2. Multiplication and division operators (*, / and %)
3. Addition and subtraction operators (and -)
4. Shift operators (> )
5. Bitwise AND operator (&)
6. Bitwise XOR operator (^)
7. Bitwise OR operator (|)
8. Logical AND operator (&&)
9. Logical OR operator (||)
10. Comparison operators (==, !=, and >= )
11. Assignment operators (=, =, -=, etc.)
12. Other operators (such as the comma operator and parentheses)

In multiplication and division operations Among operators, the multiplication operator * is used for the multiplication operation of two operands, while the division operator / is used for the division operation of two operands. Here are some specific code examples to help us understand the use of multiplication and division operators and their precedence:

package main

import "fmt"

func main() {
    a := 10
    b := 5
    c := 2
    d := 3

    // 乘法运算符
    result1 := a * b
    result2 := c * d

    fmt.Println("乘法运算结果1:", result1)
    fmt.Println("乘法运算结果2:", result2)

    // 除法运算符
    result3 := a / b
    result4 := c / d

    fmt.Println("除法运算结果1:", result3)
    fmt.Println("除法运算结果2:", result4)

    // 复合运算符
    a *= b
    c /= d

    fmt.Println("复合乘法运算结果:", a)
    fmt.Println("复合除法运算结果:", c)
}

In the above code, we have used the multiplication operator and the division operator. The multiplication operator is used to calculate the multiplication result of variables a and b and assign the results to the result1 and result2 variables respectively. The division operator is used to calculate the division result of variables a and b, and assign the results to the result3 and result4 variables respectively. Finally, we also demonstrate the use of compound multiplication and division operators.

To summarize, the highest precedence operators in the Go language are the multiplication and division operators. They have the same precedence and are higher than the addition and subtraction operators. With concrete code examples, we can better understand their usage and priorities. In the actual programming process, we can use these operators flexibly as needed.
