How to find the square in golang

Go language for squaring

Go language is an open source programming language developed by Google. It has the characteristics of static typing, automatic garbage collection and concurrent programming, so it has a wide range of applications in network programming, cloud computing and other fields.

In the Go language, finding the square of a number is also very simple. Next, we will introduce two ways to implement the square function.

Method 1: Implementation through multiplication

In Go language, you can directly use the multiplication operator "*" to realize the function of multiplying two numbers, thereby finding the square value. The following is a sample code:

package main

import "fmt"

func main() {
    var num int = 5
    var square int = num * num
    fmt.Printf("The square of %d is %d\n", num, square)
}

In the above code, we define an integer variable num and assign it a value of 5, then use num * num to find the square value, and assign the result to the square variable. Finally, use the fmt.Printf() function to output the result.

Execute the above code, the output result is as follows:

The square of 5 is 25

Method 2: Implementation through function

We can also define a square function to realize this function. The following is a sample code:

package main

import "fmt"

func square(num int) int {
    return num * num
}

func main() {
    var num int = 5
    var sq int = square(num)
    fmt.Printf("The square of %d is %d\n", num, sq)
}

In the above code, we define a function named square to find the square of a number. In the main function, we first define an integer variable num and assign it a value of 5, then find the square value by calling the square function, and assign the result to the sq variable. Finally, use the fmt.Printf() function to output the result.

Execute the above code, the output result is as follows:

The square of 5 is 25

Summary:

The function of finding squares in Go language is very simple. You only need to use the multiplication operator or define a square function Just function. At the same time, the Go language also has the characteristics of concurrent programming, allowing calculation tasks such as square calculation to be performed in a more efficient manner. Therefore, Go language has wide applications in network programming, cloud computing and other fields.
