std::vector<float>(100): 这个表达式创建了一个包含 100 个元素的std::vector<float>,所有元素都被默认初始化为0.0f(因为float的默认构造函数将其值设置为零)。 std::make_shared<std::vector<float>>(...): 这个调用会分配内存并创建一个新的std::shared_ptr<std::vector<float>>,指向上一步中生成的...
Two structs, same name, header guards, namespace but different layout (helpful w/ something that does basic checks like std:::vector) Instantiations of std::make_shared templates for both somewhere. And a call to std::make_shared for one that (hopefully) ends up going to the wrong one....
