The more explored here is the mechanism of pointers.with Debug The following procedures are analyzed to record each article C the value of the associated memory cell after the statement is run. program A.CAttention to understanding pointer

The basic idea of the cardinal sort is to sort each digit of the number, sort the digits first, and then 10 bits, hundred .... In order to sort each one, a stable sorting algorithm is required, such as the sort of counts discussed previously. Take a

Boost is a quasi-standard library, equivalent to the continuation and expansion of STL, its design concept and the STL is close to the use of generics to maximize reuse. But comparing stl,boost is more practical. The STL is concentrated in the

This is a simple template class, but in C + + there is a special syntax support, defined by the use of the following format:Initialize_list dl = {1.1, 1.2};Or:Initialize_list DL {1.1, 1.2};There are also some container classes that have constructors

A virtual function is a member function in a class that is defined in the following format:Virtual returns the type function name (parameter table).The keyword virtual indicates that the member function is a virtual function. Virtual is used only in

1. Default constructorThe default constructor either has no parameters or all parameters have default values. If no constructors are defined, the compiler will customize the default constructor.The default constructors that are automatically

What is the essence of C language, the answer to the pointer, which is the only difficulty in C language. C is very convenient for the underlying operation of the language, and the bottom of the operation of the most used is the pointer, later

Experience on C + +:Never let a constructor be called a virtual function:From the simplest thought, the C + + object model is based on the virtual function table to manage the virtual function, then when the virtual function is called, it is

An anonymous function is an "inline" statement or expression that can be used anywhere a delegate type is required. You can use an anonymous function to initialize a named delegate [delegate without a name], or to pass a named delegate (instead of a
