* strings.join // Join concatenates the elements of a to create a single string. The separator string // sep is placed between elements in the resulting string. func Join(a []string, sep string) string { switch len(a) { case 0: return "" case 1: return a[0] case 2: // Special...
第5步 --该函数使用join()库函数来进行相应的转换。最后,我们需要使用fmt.Println()函数在屏幕上打印字符串的值和它的类型。例子Golang程序使用join()函数将一个数组转换为字符串。package main import ( "fmt" "reflect" "strings" ) // function to convert an array to...
// Join concatenates all elements of Array, Slice or String to a single string with a separator. func Join(a any, sep string) string { s, _ := JoinE(a, sep) return s } 我们使用不同类型的切片来验证一下。 代码语言:javascript 代码运行次数:0 运行 AI代码解释 package main import ( "...

vars string// 字符串类型的零值是空串 "" ifs ==""{ s ="default" } } 12. Array 类型的值作为函数参数 在C/C++ 中,数组(名)是指针。将数组作为参数传进函数时,相当于传递了数组内存地址的引用,在函数内部会改变该数组的值。 在Go 中,数组是值。作为参数传进函数时,传递的是数组的原始值拷贝,此时...
