Keyword typename In the process of C ++ standardization, the keyword typename is introduced for illustration; the identifier inside the template can be a type. For example: template In the above program, the 2nd typename is used to describe that subtype is a type defined within Class T. Therefore, PTR is a pointer to the T: subtype type. If you do not use typename, subtype will be considered as a static mem
1. Template meta-programming (MATAPROGRAMMING,TMP) is the process of writing a C + + program and executing it at compile time, "the so-called template Mataprogram (templated meta-Program), is written in C + +, executed in C + + The program within the compiler. Once the TMP program finishes executing, its output, that is, a number of C + + sources from templates,
Recently, I have been studying C + + template programming, although some difficulties, but hope to persist. Today, in the book to see a discussion template programming TypeName and class two keyword difference, think very meaningful, they summed up.Let's look at an example:TemplateC) { typedef typename C::value

function templatesRoleThere are many times when the type of the parameter and the type of the return value is variable, and we define the template to make the function more flexible to use.We design a comparison function, if we can compare the two parameters are int, two parameters may be string type, separate design two comparison function will be more cumbersome, at this time, we use the function template.Templateint cmp (t A, T b) {Return a>b;}(1)

Generic programming and C ++ Standard Template Library: Talking About sort () sorting function and sort Previously, when sorting With sort, we only know that the sort function has the following two overload methods. At that time, I was not very familiar with these parameters. I only knew some simple usage. 1). For example, the following code can arrange array a in ascending order. Int a [5] = {1, 6, 9, 4,
2.3If substitutionThe IF statement is executed at compile time and can be implemented in a template-specific way. Here is the calling code:Test ifcout The output is:Test Ifit ' s falseThe implementation of the template class is as follows:TemplateC + + template meta-programming four: If statement runs at compile time
ABP is a starting point for using best practices and using the most popular tools for new modern web applications.

C + + supplements--template meta-programmingPrefaceThe template element is used for recursive acceleration, which changes the run-time function call to the compile time for code expansion, similar to an inline function. Here is an example: the Fibonacci sequence nth solution.template meta-programming#include RunSummary:Recursive method takes a long time. The runt
Class templateWhen defining a class, you can also abstract some types and replace them with template parameters, making the class more versatile. This class is called a template class, for example:Template {T data;PublicHow class template member functions are defined one: defined in a class templatevoid print () {cout }How class
2.2Loop unrolling Looping expansionThe previous enum section describes the combination with the template, which throws a magical effect on the compiler recursion. The template itself can achieve recursive results without the need for enum mates.Test template recursive for loop unrolling cout The output is:Test 2:template
