Question

这可能是一个愚蠢的问题，我对编码仍然很陌生。对于我的CS课程，我获得了桌面游戏基础知识的代码。当我尝试运行代码时，它只是在我的控制台中显示为空白，我尝试打印＆＃34;检查＆＃34;在main的最开始，但仍然没有打印到控制台。没有错误出现

#include <iostream>
#include <string>
#include <fstream>
#include <ctime>
#include <cstdlib>

private:
    int move;
    string message;
    char symbol;
public:
    square();
    void print();
    int action();
    void set(int, char, string);
};

void print_board(square[], int, int);
void read_board(square[]);
void check_position(int &);

const int board_length = 20;

int main() {
    cout << "check";
    int current_player = 1, roll;
    int player1_position = 0, player2_position = 0;
    square the_board[board_length];
    srand(time(NULL));

Answer 1

将read_board（）修改为

   void read_board(square b[]) {
        ifstream infile;
        infile.open("game.txt");
        int square_number, square_move;
        string square_message;
        char square_symbol;
        while (infile >> square_number >> square_move >> square_symbol) {
            getline(infile, square_message);
            if (square_number < board_length) {
                b[square_number].set(square_move, square_symbol, quare_message);
            }
        }
    }

Answer 2

将cout<<"check";更改为cout<<"check"<<endl;

如果没有添加新行，则在您的代码在read_board函数中挂起之前不会刷新out缓冲区

程序运行时，C ++控制台为空
