多维字符串数组赋值 C++

Question

我有一个预先分配的多维字符串数组，声明如下：

std::string test[5][169] = { { },{ },{ },{ },{ } };

我需要创建一个函数，接受这样的字符串作为输入：

{"abc","dac","fab" },{"hbv","acd" },{ "ccd","ahn","agt","atr"},{"are"},{ }

并将正确的值放入数组中（正如我正在分配的那样）；

问题是我不能将 2D+ 数组作为参数传递给 C++ 中的函数 并且不能像这样对多维数组进行赋值：

test= {"abc","dac","fab" },{"hbv","acd" },{ "ccd","ahn","agt","atr"},{"are"},{ };

我正在寻找一种将值正确放入数组的方法。

我也尝试过使用std::vector，我只为一维数组解决了这个问题：

std::vector<std::string> test;
test = {"abc","dac","fab" };

但我需要类似的东西

std::vector< std::vector<std::string> > test;
test = {"abc","dac","fab" },{"hbv","acd" },{ "ccd","ahn","agt","atr"},{"are"},{ };

Answer 1

在你的最后一行添加一对额外的大括号，你应该完成：

 test = {{"abc","dac","fab" },{"hbv","acd" },{ "ccd","ahn","agt","atr"},{"are"},{ }};
