Function call

When you create a function, you define what the function needs to do and call the function to perform the specified task.

Call the function, pass parameters to the function, and return a value, such as:

Example

Package main

Import "fmt"

Func main () {

/ * define local variables * /

Var an int = 100

Var b int = 200

Var ret int

/ * call the function and return the maximum value * /

Ret = max (a, b)

Fmt.Printf ("maximum is:% d\ n", ret)

}

/ * the function returns the maximum of two numbers * /

Func max (num1, num2 int) int {

/ * define local variables * /

Var result int

If (num1 > num2) {

Result = num1

} else {

Result = num2

}

Return result

}

The above example calls the max () function in the main () function, and the execution result is:

The maximum value is: 200. so far, I believe you have a deeper understanding of "how to call Go language functions". You might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
