Binary sort tree is a tree table which realizes dynamic search , also called two-fork search tree .The nature of the binary sort tree:1. If its left subtree is not empty, the key value of all nodes on the left subtree is less than its root node key

ASSERT preprocessing macrosAssert is a preprocessing macro, so-called preprocessing is actually a preprocessing variable that behaves like an inline function, and an Assert macro uses an expression as its condition:ASSERT (expr)The first is to

Dynamic arraysEach program consumes a piece of available memory space at execution time, which is used to hold dynamically allocated objects, which are called free stores of programs or heaps (heap). The C language uses malloc and free to allocate

C + + provides a keyword explicit that prevents the occurrence of implicit conversions that should not be allowed by a transformed constructor. A constructor declared as explicit cannot be used in an implicit conversion.In C + +, a constructor for a

Don't let exception escape destructor Prevent exceptions from leaving destructorsDestructors should never throw an exception, and if a function called by a destructor might throw an exception, the destructor should handle the exception and not throw

1. In multiple inheritance, the order in which the base classes are constructed is consistent with the order in which the base classes appear in the list of derived classes, regardless of the order in the list of initial values.2. In the new c++11
