C++ 字符串字面量数据类型存储
void f()
{
char *c = "Hello World!"
}
字符串存储在哪里?它的属性是什么?我只知道它是一个常数，还有什么?我可以从函数体内部返回它吗?
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
它与你的二进制文件打包在一起――我所说的打包是指硬接线，所以是的，你可以返回它并在其他地方使用它――你不会能够改变它，我强烈建议你将其声明为:
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";
