第一章,“音频概念”,涵盖了一些最重要的音频概念,如声波、模拟和数字音频、多声道音频和音频文件格式。 第二章,“音频播放”,展示了如何使用 FMOD 加载和播放音频文件,以及如何开始创建一个简单的音频管理器类。 第三章,“音频控制”,展示了如何控制声音的播放和参数,以及如何将声音分组到类别并同时控制它们。 第...
C++ 标准始终禁止 const 元素(如 vector<const T> 或set<const T>)的容器。 Visual Studio 2013 及更早版本接受此类容器。 在当前版本中,此类容器无法编译。 std::allocator::deallocate 在Visual Studio 2013 和早期版本中,std::allocator::deallocate(p, n) 忽略了传入用于 n 的参数。 C++ 标准始终要求 n...
The C++ standard has always forbidden containers of const elements (such as vector<const T> or set<const T>). Visual Studio 2013 and earlier accepted such containers. In the current version, such containers fail to compile. std::allocator::deallocate In Visual Studio 2013 and earlier, std::...
使用:int* const p = function7(); static 作用 修饰普通变量,修改变量的存储区域和生命周期,使变量存储在静态区,在 main 函数运行前就分配了空间,如果有初始值就用初始值初始化它,如果没有初始值系统用默认值初始化它。 修饰普通函数,表明函数的作用范围,仅在定义该函数的文件内才能使用。在多人开发项目时,...
