嗨我遇到一些問題，當我嘗試編譯我的3個文件，main.cpp，My_Stack.cpp和My_Stack.hpp如果我沒有包含頭文件，並且在main.cpp中添加了「#include」My_Stack.cpp「」而不是「#include」My_Steak.hpp「」，那麼「Undefined symbols for architecture x86_64」錯誤精細。未定義的符號體系結構x86_64錯誤在c + +中，頭顯然沒有鏈接
//main.cpp
#include <iostream>
#include "My_Stack.hpp"
int main(int argc, const char * argv[]) {
My_Stack<int> s = My_Stack<int>();
s.push(1);
s.push(2);
cout << s.pop() << endl;
cout << s.pop() << endl;
}
