C++ 模板类用法

#include <vector>
#include <stdexcept>
#include<string>



template <typename T1, typename T2>
class Pair {
private:
    T1 first;
    T2 second;

public:
    Pair(const T1& f, const T2& s) : first(f), second(s) {}

    T1 getFirst() const { return first; }
    T2 getSecond() const { return second; }

    void setFirst(const T1& f) { first = f; }
    void setSecond(const T2& s) { second = s; }
};

int pairTest() {
    Pair<int, std::string> p1(1,"str");
    return 0;
}


template <typename T>
class Stack {
private:
    std::vector<T> elements;

public:
    void push(const T& element) {
        elements.push_back(element);
    }
};

void StackTest()
{
    Stack<int> stack1;
    Stack<std::string> stack2;
}



int main() 
{
    pairTest();
    StackTest();
    getchar();
    }
