C ++字符串文字数据类型存储 [英] C++ string literal data type storage

问题描述

void f()
{
    char *c = "Hello World!"
}

字符串存储在哪里？它的属性是什么？我只知道这是一个常数，还有什么？我可以从函数体内部返回它。

Where is the string stored? What's the property of it? I just know it is a constant, what else? Can I return it from inside of the function body?

推荐答案

它与你的二进制包装 - 有线，所以是的你可以返回它，并使用它在其他地方 - 你将无法改变它，但我强烈建议你声明它：

it is packaged with your binary -- by packaged I mean hard-wired, so yes you can return it and use it elsewhere -- you won't be able to alter it though, and I strongly suggest you declare it as:

const char * x = "hello world";
