编程实例的模板可以根据不同的编程语言和用途有不同的结构和内容。以下是一些常见编程语言中编写模板的示例:
1. C++ 模板类示例
```cpp
// array.h
ifndef ARRAY_H
define ARRAY_H
template class array { T data_[SIZE]; public: array() {} array(const array& other) { std::copy(other.data_, other.data_ + SIZE, data_); } const array& operator=(const array& other) { if (this != &other) { std::copy(other.data_, other.data_ + SIZE, data_); } return *this; } T& operator[](int i) { return data_[i]; } const T& get_elem(int i) const { return data_[i]; } void set_elem(int i, const T& value) { data_[i] = value; } operator T*() { return data_; } }; endif // ARRAY_H ``` 2. C++ 函数模板示例 ```cpp // main.cpp include "array.h" include int main() { array intArray.set_elem(0, 2); int firstElem = intArray.get_elem(0); int* begin = intArray; std::cout << "First element: " << firstElem << std::endl; std::cout << "Begin pointer: " << begin << std::endl; return 0; } ``` 3. VSCode 代码片段示例 在 VSCode 中,你可以创建自定义的代码片段来提高开发效率。以下是一个简单的 Vue 模板示例: ```cpp // swap.h ifndef SWAP_H define SWAP_H template void swap(T& a, T& b) { T tmp = a; a = b; b = tmp; } endif // SWAP_H ``` 4. 程序文件编写模板示例 ```cpp // main.cpp include "swap.h" include int main() { int nNum1 = 50; int nNum2 = 30; double dfNum1 = 2.1; double dfNum2 = 3.0; char* pszFirst = "Hello"; char* pszSec = "world!"; swap(nNum1, nNum2); swap(dfNum1, dfNum2); swap(pszFirst, pszSec); std::cout << "nNum1 = " << nNum1 << ", nNum2 = " << nNum2 << std::endl; std::cout << "dfNum1 = " << dfNum1 << ", dfNum2 = " << dfNum2 << std::endl; std::cout << "pszFirst = " << pszFirst << ", pszSec = " << pszSec << std::endl; return 0; } ```
