cpp: 指针和引用(class & object) 一、指针使用、引用的运用 1、指针具有双重赋值的属性:第一重赋值,为指针变量赋值内存地址;第二重赋值,为指针变量所指的内存的存储空间赋予内容。 2、(引用:cpp的特性;“引用”作为函数的参数):"引用"仍然是值传递。和普通变量相比较,“引用”只是不产生变量的临时副本。 1[r...
The type code for any ref class besides Platform::String is Object (1).The Windows::UI::Xaml::Interop::TypeName class is used in the Windows APIs as a language-independent way of passing type information between Windows components and apps. The TPlatform::Type Class has operators for ...

before any of your implementations in a .CPP file, then the third version of delete will be used, storing the filename and line number in the allocated block for later reporting. You don't have to worry about supplying the extra parameters; a macro takes care of that for you....
