How to pass parameters to Go function

This article mainly explains "how to pass parameters to the Go function". Interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Next let the editor to take you to learn "Go function how to pass parameters" bar!

Function parameter

If a function takes an argument, the variable can be called a formal parameter of the function.

A parameter is like a local variable defined in the body of a function.

To call a function, you can pass parameters in two ways:

Passing type description values passing values means that a copy of the actual parameters is passed to the function when the function is called, so that if the parameters are modified in the function, the actual parameters will not be affected. Reference passing refers to passing the address of the actual parameter to the function when calling the function, so the modification of the parameter in the function will affect the actual parameter.

By default, the Go language uses value passing, which means that the actual parameters are not affected during the call.

Function usage function usage description function is defined as an argument function of another function and can be passed into the closure as a real parameter of another function. The closure is an anonymous function, but in dynamic programming, the method is a function that contains the recipient. What is suitable for go is the abbreviation of golang, and golang can do server-side development. And golang is very suitable for log processing, data packaging, virtual machine processing, database agent and other work. In the aspect of network programming, it is also widely used in web applications, API applications and other fields.
