将C cstyle 数组视为 std::array问题描述 投票:0回答:4是否有任何安全且符合标准的方法将 C 样式数组视为 std::array 而不将数据复制到新的 std::array 中? 这显然无法编译,但却是我想要的效果(我的实际使用更复杂,但这个简短的示例应该显示我想要做什么)。我猜reinterpret_cast会“起作用”,但可能不安全...

The [] marshal([+2]) says it should be passed as a C-Style array. The marshal “+2” part is a zero-based index which tells the interop layer which method parameter contains the size of the arrays. In this case, +2 turns out to be the size parameter. 9. Now we’ll change ...
声明一个伸缩型数组成员(flexible array member)具有如下规则: 伸缩性数组成员必须是结构的最后一个成员 结构中必须至少有一个成员 伸缩数组的声明类似于普通数组,只是方括号中是空的 代码语言:javascript 代码运行次数:0 运行 复制 struct flex { int count; double average; double scores[]; //伸缩型数组成员 ...

Because C-style strings are C-style arrays, you can usestd::size()(or in C++20,std::ssize()) to get the length of the string as an array. There are two caveats here: This doesn’t work on decayed strings. Returns the actual length of the C-style array, not the length of the ...
