There is a good way to implement the builder pattern in Java. The builder mode is implemented here using C + + in the Java version.In C + +, inner and outer classes are not directly related, and private objects of external classes cannot be accessed

When the program is compiled, all pre-processing commands are processed, replacing the specific contents of the header file with the # include command line, and then compiling the program unit as a whole. using namespace Std; "Use command space Std"

VECOTR is a dynamic array, as the name implies, he can dynamically increase his own length.Memory mechanism:But how to increase their length?Vector has two functions one is capacity () returns the memory space that is the size of the buffer, and the

First of all, let's look at the picture! The orange represents the variable, using the private adornment. , assume that the variable name of the person class can only be entered by using the input method. Then the s_input and T_input functions in

In the past, few deletions have been done, vectors have always been used as arrays, while the actual pursuit of efficiency often discards vector selection of C-style arrays. See "C + + Primer" to sequential containers delete this section try to

The Kmean algorithm that used the OPENCV was also practiced, but the version was low and was based on C development. These two days because of the need to create a paper to re-turn it out in the study of C + +, found some improvementsKmeans
