Initialization Order of Golang

This is a created article in which the information may have evolved or changed. Init Each package can define one or more init function 2 (prototype is func init ()), the Init function is called when the package is first imported, the sequence of execution of multiple init functions within the same package is variable, and if the package imports another package, the Cascade call, All packages import is complete, and after all the Init functions are executed, the execution of main begins.  And for global variables, take a simple example to illustrate: //package P var gInt int ...  //Package a import "P" ...  //package B import "P" ...  //package main import ("a" "B") ... in package p, we define a global variable gint, and P is import by the package A, B, and then packagemain and then import a A, B, which is the import of a in front. A imports the P first, so at this point the Gint is initialized, which solves the problem of inconsistent initialization order of global variables in C + +.
