The Go language is designed as a systems programming language for use on giant central servers that power web servers, storage clusters, or similar purposes.
For the field of high-performance distributed systems, the Go language undoubtedly has higher development efficiency than most other languages. It provides massive parallel support, which is perfect for game server development.
Go language functions syntax
Functions are basic blocks of code that perform a task.
The Go language has at least a main() function.
You can divide different functions by functions. Logically, each function performs a specified task.
The function declaration tells the compiler the name, return type, and parameters of the function.
The Go language standard library provides a variety of built-in functions that can be used. For example, the len() function can accept arguments of different types and return the length of that type. If we pass in a string, the length of the string is returned. If we pass in an array, the number of elements contained in the array is returned.
Go language functions example
/* Function returns the maximum value of two numbers */
func max(num1, num2 int) int {
/* Declare local variables */
var result int
if (num1 > num2) {
result = num1 } else {
result = num2 }
return result
}
