This article is a detailed introduction to "what is the method of C++ generic programming". The content is detailed, the steps are clear, and the details are properly handled. I hope this article "what is the method of C++ generic programming" can help you solve your doubts. Let's go deeper and learn new knowledge together with the ideas of Xiaobian.

Let's first look at the characteristics of data structures: 1) focusing on relationships between data elements;2) focusing on algorithms on specific structures. The data structure does not care about the specific type of data element!

So how do you choose the right language for data structure learning? We've seen C data structures before, and there are C++ data structures. But from a coupling perspective, languages that support generic programming are best suited for learning data structures. Generic programming refers to programming that does not consider specific data types. For Swap functions, consider writing generic as follows

void Swap(T& a, T& b){ T t = a; a = b; b = t;}

Swap generic writing T is not a specific data type, but refers to any data type, so we can not reuse the code, do not have to repeat the brick. Generic programming corresponds to function templates in C++, which are special functions that can be called with different types. It looks similar to a normal function, except that the type can be parameterized. The function template format is as follows

template

void Swap(T& a, T& b){ T t = a; a = b; b = t;}

Let's take a look at the syntax rules of function templates: 1. The template keyword is used to declare the beginning of generic programming;2. The typename keyword is used to declare a generic type. as shown in the following figure

Let's take a look at the use of function templates: 1. Automatic type push calls;2. Specific type display calls. as follows

int a = 0;int b = 1;Sawp(a, b); //float c= 2;float d = 3;Swap(c, d); //Show call

Let's take code as an example to illustrate

#include using namespace std;template

void Swap(T& a, T& b){ T t = a; a = b; b = t;}template

class Op{public: T process(T v) { return v * v; }};int main(){ int a = 1; int b = 2; Swap(a, b); cout
