解决方案:switch 表达式类型应为 int 或 char error C2466: cannot allocate an array of constant size 0 中文对照:(编译错误)不能分配长度为 0 的数组 解决方案:一般是定义数组时数组长度为 0 error C2601: 'xxx' : local function definitions are illegal 中文对照:(编译错误)函数 xxx 定义非法 解决方案:...
C 语言中允许结构体的最后一个字段为未指明长度的数组类型,该数组被称为柔性数组(flexible array),仓颉不支持包含柔性数组的结构体的映射。字符串 特别地,对于 C 语言中的字符串类型,仓颉中设计了一个 CString 类型来对应。为简化为 C 语言字符串的操作,CString 提供了以下成员函数: init(p: CPointer<UInt8>)...

Second, <tuple> now declares std::array without including all of <array>, which can break code through the following combination of code constructs: your code has a variable named "array", and you have a using-directive "using namespace std;", and you include a C++ Standard Library ...

build flags is a array-like flags after the arch-abi, there will be two ways to arrange them, aka AND, OR operation. If you would like the flags in build flags array acts on arch-abisimultaneously, you can use:to separate them. For example: ...
