Question

我如何在屏幕上打印 std:: victor 的内容?

执行以下 operator<< 的解决方案也不错:

template<container C, class T, String delim = ", ", String open = "[", String close = "]">
std::ostream & operator<<(std::ostream & o, const C<T> & x)
{
  // ... What can I write here?
}

以下是我迄今拥有的,没有单独的功能:

#include <iostream>
#include <fstream>
#include <string>
#include <cmath>
#include <vector>
#include <sstream>
#include <cstdio>
using namespace std;

int main()
{
    ifstream file("maze.txt");
    if (file) {
        vector<char> vec(istreambuf_iterator<char>(file), (istreambuf_iterator<char>()));
        vector<char> path;
        int x = 17;
        char entrance = vec.at(16);
        char firstsquare = vec.at(x);
        if (entrance ==  S ) { 
            path.push_back(entrance); 
        }
        for (x = 17; isalpha(firstsquare); x++) {
            path.push_back(firstsquare);
        }
        for (int i = 0; i < path.size(); i++) {
            cout << path[i] << " ";
        }
        cout << endl;
        return 0;
    }
}

int main() {
    std::cout << nlohmann::json(std::vector<int>{1, 2, 3}) << std::endl;
    std::cout << nlohmann::json(std::vector<int>{1, 2, 3}).dump() << std::endl;
    std::cout << nlohmann::json(std::vector<std::string>{"hello", "world"}) << std::endl;
