多维字符串数组赋值C ++

Question

我有一个预分配的多维字符串数组，声明如下：

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

我需要创建一个接受如下输入的函数的函数：

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

并在数组中放入正确的值（因为我正在分配它）;

问题是我无法将2D +数组作为参数传递给C ++中的函数 并且不能像这样分配多维数组：

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

我正在寻找一种方法将正确的值放入数组中。

我也尝试使用std::vector，我只解决了一维数组的问题：

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

但我需要像

这样的东西

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大括号，你应该完成：

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