按引用传递的std ::字符串的数组 [英] Passing a array of std::string by reference

问题描述

I'ld喜欢创造传递不通过引用一个std :: string要修改的功能，

I'ld like to create a function that passes not a std::string by reference to be modified,

void changeStr(std::string &str)
{
    str = "Hello World!";
}

，而是一个完整的，固定大小的std ::字符串（函数会做同样的：一些属性特定字符串的每个空间阵列中）的阵列。但我不知道这是适当的语法...

, but rather an entire, fixed-sized array of std::strings (the function will do exactly the same: attribute some specific strings to each space in the array). But I don't know which is the appropriate syntax...

推荐答案

下面是如何！

//Change the 10 to whatever size you'd like
void changeStr(std::string (&str)[10]) {
}

这当然是一个静态的大小，其他的答案，但是，是的更好的方法完成你需要灵活的。

This of course, is for a static size, the other answers, however, are better methods accomplishing what you need with flexibility.
