This article will explain in detail how to use the meta programming language in C++. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

Template

As template metaprogramming needs to be object-oriented, if you have any questions, you can first add a little object-oriented knowledge of C++:

The object-oriented article of C++ is enough.

Preliminary generics

Because C++ is a statically strongly typed language, once a variable is created, the type cannot be changed. If we want to create a plural type that is widely used, it is troublesome to create one by one based on the basic types such as int, float, and double. Generic programming is designed to simplify this process.

A class that can hold different data types as members is called a template class, and its basic method is to add a line of template declaration code to the class declaration.

Template, the next behavior class myClass, whose calling procedure is myClass m.

Examples are listed as follows

# includeusing namespace std;templatestruct Abstract {C real; / / real is C type C im; Abstract (C inReal, C inIm) {real = inReal; im = inIm;} void printVal () {cout
