stack with template

 template가 뭔가 했는데 그냥 generic이네, 근데 편하다

#include<iostream>
 
using namespace std;
 
template<class T>
class stack {
private:
    T stk[10];
    int sp = 0;
public:
    void push(T val);
    T pop();
};
 
template <class T>
void stack<T>::push(T val){
    stk[sp++] = val;
};
 
template <class T>
T stack<T>::pop(){
    T tmp = stk[sp];
    stk[sp--] = NULL;
    return tmp;
};
 
int main() {
    stack<float> sk;
    sk.push(10);
    sk.push(6.24);
 
    cout << sk.pop() << endl;
    cout << sk.pop() << endl;
    system("pause");
    return 0;
}
