但是我不知道为什么。...我的猜测正在链接，但是我已经检查了标头，但我仍然看不到它

我的代码

#include <iostream>

#include <iomanip>
#include "BST.h"
using namespace std;

int main()
{

    BST<char> op1;
    int action = 0;
    int numInsert = 0;
    char value;

cout<<"-------------------- MENU ----------------------"

            case 1:
                cout << "\n How many values would you liek to insert to a BST? ";
                cin>>numInsert;
                for(int i =0; i<numInsert;i++){
