直接存储数据本身：值类型直接在内存中存储具体的值。分配在栈上：大多数情况下，值类型的实例存储在栈上，这使得它们的内存分配和释放非常高效。存储引用而非数据本身：引用类型存储的是指向实际数据的内存地址（即引用），而不是数据本身。分配在堆上：引用类型的实例存储在堆上，而引用本身则存储在栈上。性能：值类型通常更快，因为它们直接存储在栈中，而引用类型涉及额外的间接寻址。内存消耗：值类型在频繁复制时可能会消耗更多内存；引用类型则可能因对象的生命周期管理不当导致内存泄漏。使用场景。

个人观点：静态库就是可执行代码，就是平时写的某个c文件：头+c源文件。只不过不是为了引用作为库，而写静态连接库就是把(lib)文件中用到的函数代码直接链接进目标程序，程序运行的时候不再需要其它的库文件；动态链接就是把调用的函数所在文件模块（DLL）和调用函数在文件中的位置等信息链接进目标程序，程序运行的时候再从DLL中寻找相应函数代码，因此需要相应DLL文件的支持。
