查找使用constexpr的代码行: 在C语言文件中找到所有使用constexpr的地方。例如: c constexpr int MAX_SIZE = 100; // 这行代码在C语言中会导致编译错误 替换constexpr为C语言中合法的关键字或移除它: 由于C语言不支持constexpr,我们需要移除它,或者使用C语言中的其他机制来实现相同的功能。如果constexpr用于...

But in many cases you don't know that length at compile time so you can't use such a struct. What is usually done in such cases is to declare a struct where the array size is 0 or 1 and then you need to allocate memory you have to manually calculate the size in bytes by doi...
