This is my first time to write a blog, mainly to record their own learning process, experience, one can be convenient to review the relevant knowledge, second, we can learn from each other exchange.Regarding the overloading, overwriting, and hiding

Today do C + + primer exercises, by the copy constructor and the difference between the assignment is dizzy. To put it simply, there is a topic that is described as follows:class T1;Class t2 = t1;I first saw an equal sign, which I thought was the

1. Default access modifiers for elements under namespacesPublic: Any other code of the same assembly or other assemblies that reference the assembly can access the type or member.Internal: Any code in the same assembly can access the type or member,

IntroductionA tree is a nonlinear structure. The essence of a tree is to connect some nodes by edges to form a hierarchical structure. The binary tree is a special kind of tree, so that each child node of the tree must be less than or equal to 2.

A method signature consists of a method name and a list of parameters (the number, order, and type of the method's parameters).Note: The signature of the method does not include the return value and modifiers of the method.In C #, two or more two or

When using (UINT)-1, the compiler gives a warning: constant-1 cannot be converted to uint, and is overridden with the unchecked statement. A DWORD is a uint when converted to C # types, and since it cannot be forced to transform with uint (-1), it

C # will need to handle the mapping of C structures to C # structures when accessing the win + API, which can be found on MSDN and many blogs. In Win 32, there are some complex structs that have fixed-length arrays or some special structures, such

There are two ways to define constants in C #, one is called a static constant (Compile-time constant), and the other is a dynamic constant (Runtime constant). The former is defined by "const", which is defined by "ReadOnly". For static constants
