需要注意的是for+rang遍历string时得到的是字节索引位置和UTF-8格式rune类型数据(int32)。 for pos, value := range "Go在中国" { fmt.Printf("character '%c' type is %T value is %v, and start at byte position %d \n", value,value,value, pos) str :=string(value) //convert rune to stri...
// Convert the rune slice back to a string and return it. return string(runes) } 解释: ReverseString函数:该函数接收一个字符串参数并返回其反转值。它将字符串作为 rune 切片而不是字节来处理,这对于正确处理大小可能超过一个字节的 Unicode 字符至关重要。

Integers and strings are converted to each other on many different occasions. This post will provide the ways we can convert an integer to a string in Go. The naive typecasting We may try doing a simple type conversion using the string() function to convert an integer to a string. It ...
