std::string为library type,而int、double为built-in type,两者无法互转,这里使用function template的方式将int转std::string,将double转std:string。 1 /* 2 (C) OOMusou 2006http://oomusou.cnblogs.com 3 4 Filename : ArrayToVectorByConstructor.cpp 5 Compiler : Visual C++ 8.0 6 Description : Demo...
现在我们已经收集了足够的信息,可以开始讨论 CMake 的核心功能:构建项目。在 CMake 中,一个项目包含管理将我们的解决方案带入生活的所有源文件和配置。配置从执行所有检查开始:目标平台是否受支持,是否拥有所有必要的依赖项和工具,以及提供的编译器是否工作并支持所需功能。 完成后,CMake 将为我们的选择构建工具生成...

You'll also need to update the calls to placement new to pass the new type (for example, by using static_cast<my_type> to convert from the integer value) and update the definition of new and delete to cast back to the integer type. You don't need to use an enum for this; a ...
