如何根据模板类型参数调用不同的函数？

#include <iostream>

template<typename T>
void process(T value) {
    std::cout << "Generic process function: " << value << std::endl;
}

template<>
void process<int>(int value) {
    std::cout << "Specialized process function for int: " << value << std::endl;
}

template<>
void process<double>(double value) {
    std::cout << "Specialized process function for double: " << value << std::endl;
}

void process(int value) {
    std::cout << "Overloaded process function for int: " << value << std::endl;
}

void process(double value) {
    std::cout << "Overloaded process function for double: " << value << std::endl;
}

int main() {
    process(10);      // 调用特化的 process<int> 函数
    process(3.14);    // 调用特化的 process<double> 函数
    process(20);      // 调用重载的 process(int) 函数
    process(2.718);   // 调用重载的 process(double) 函数

    return 0;
}

Specialized process function for int: 10
Specialized process function for double: 3.14
Overloaded process function for int: 20
Overloaded process function for double: 2.718
