go为什么不能获取字符串某个字符地址？

Question

go为什么不能获取字符串某个字符地址？go如此设定的目的是什么？

Answer 1

这个是go的字符串规定的，因为它是immutable类型，所以让你取某个字符的地址，官方不觉得有啥意义

A string type represents the set of string values. A string value is a (possibly empty) sequence of bytes. Strings are immutable: once created, it is impossible to change the contents of a string. The predeclared string type is string.

The length of a string s (its size in bytes) can be discovered using the built-in function len. The length is a compile-time constant if the string is a constant. A string's bytes can be accessed by integer indices 0 through len(s)-1. It is illegal to take the address of such an element; if s[i] is the i'th byte of a string, &s[i] is invalid.
