Abstract:This article describes a common situation: When you store data in a cache, you often need to adjust the cache size at runtime to accommodate more data. This article will discussHow to Use STL vector for memory redistribution.The following

A loop has a similar structure: Condition judgment, and the loop body. Its base class is as follows: public class Loop : ControlFlow { public Expression.ExpressionNode Condition; public virtual Block Body { get {

In my spare time, I added support for the structure. Added support for typedef structname synonym. TIPS: 1. structure members are converted to the offset relative to the starting address of the structure during parsing. 2. Calculate the actual

Event support is already one of the subsequent language syntaxes such as Delphi, Java, and C #, but it is not shown in C ++. Different compilers use their own methods to support events. For example, Borland C ++ Builder provides event support
