In themain()function, we created two string variablesstr1,str2. After that, we usedstrings.LastIndex()function to get the last index of a specified substring in the specified string. If the substring is not found in string thenstrings.LastIndex()function will return -1....
func GetName() (firstName, lastName, nickName string) { return"May", "Chan", "Chibi Maruko"} _, _, nickName := GetName 函数调用 函数调用非常方便,只要事先导入该函数所在的包,就可以调用了: import "mymath"c := mymath.Add(1,2) 注意:小写字母开头的函数只在本包内可见,大写字母开头的函...
we usedstrings.IndexByte()function to get the index of a specified character in the specified string. Thestrings.IndexByte()function return the integer value. If the specified character is not found in the string then it will return -1....

go把每一个能异步并发的操作,像你说的文件访问啦,网络访问啦之类的都包包好,包成一个看似朴素的而且是同步的“方法”,比如string readFile(我瞎举得例子)。但是神奇的地方在于,这个方法里其实会调用“异步并发”的操作,比如某操作系统提供的asyncReadFile。你也知道,这种异步方法都是很快返回的。 所以你自己在某...
