编译错误c ++标准文件流

Question

#include <iostream>
#include <fstream>
#include <string>
using namespace std;

int main() {
    std::ifstream ifs;
    std::ofstream ofs;
    std::string input;

    // ask for input file and output file
    std::cout << "Enter input file name: " << std::endl;
    std::cin >> input;
    ifs.open(input);
    if (ifs.fail()) {
        std::cout << "Failed to open the input file." << std::endl;
        return 1;
    }
    std::cout << "Enter output file name: " << std::endl;
    std::cin >> input;
    ofs.open(input);
    if (ofs.fail()) {
        std::cout << "Failed to open the output file for write access." << std::endl;
        return 1;
    }

    // read the count of node and link
    int node_count = 0;
    int link_count = 0;
    ifs >> node_count;
    ifs >> link_count;

    // alloc and zero memory
    int *nodes = new int[node_count];
    int *links = new int[link_count];
    for (int i = 0; i < node_count; ++i) { nodes[i] = 0; }
    for (int i = 0; i < link_count; ++i) { links[i] = 0; }

    while (!ifs.eof()) {
        bool gg = false;
        for (int i = 0; i < link_count; ++i) {
            ifs >> links[i];
            nodes[(links[i] / 10) - 1] = 1;
            nodes[(links[i] % 10) - 1] = 1;
        }
        for (int i = 0; i < node_count; ++i) {
            if (nodes[i] == 0) {
                gg = true;
                break;
            }
        }
        if (!gg) {
            for (int i = 0; i < link_count; ++i) {
                ofs << links[i] << " ";
            }
            ofs << std::endl;
        }
    }
    delete[] nodes;
    delete[] links;
    ifs.close();
    ofs.close();
}

当我编译这个c ++程序并运行得到这个错误。没有匹配调用std :: basicifstream :: open（st ...，有人可以帮我吗？这是我不应该使用std ::？并直接使用ifs直接
