If 语句未完成代码并跳过获取用户输入

Question

#include <iostream>
#include <cstdlib>
#include <crime>
#include <stream>
#include <cmath>
using namespace std;

char game;
char username;
char passwordOnline;
int password = 2427;
int password2 = 2724;
int answer1;
int answers;



int main()
{
cout << "Hello Welcome to PasswordHolder by ItsScrandy \n";
cout << "Please Enter The First Password: \n";
cin >> answer1;
cout << "Please Enter The Second Password \n";
cin >> answer2;

if (answer1 == password && answer2 == password2)
{
    cout << "What Is The Game Called? \n";
    cin >> game;

    cout << "What Is The Username/Email? \n";
    cin >> username;

    cout << "What Is The Password? \n";
    cin >> passwordOnline;
  }
    if (answer1 == password || answer2 == password2)
    {
        cout << "One of the password's you have enterd is incorrect";

    }
    else {
        cout << "Wrong Password";
    }

    //creating a .txt file 
    ofstream pctalk;
    pctalk.open("Login Details.txt", ios::app);

    //actually logging
    pctalk << "Game: " << game << " | " << "Username/Email: " << username << " | " << "Password: " << 
passwordOnline << "\n";
    //closing our file
    pctalk.close();
    return 0;
}

当我运行编码时，我的程序似乎运行良好，直到它要求用户提供游戏。获得输入后它自动运行s if 语句的其余部分。然而，如果语句被 bing 跳过，而其余代码运行则发生的是辅助输入。谁能告诉我为什么这些 if 语句没有正确执行？

Answer 1

您正在对密码的第一条和第二条语句进行相同的评估。在第一个声明中：

if (answer1 == password && answer2 == password2)

第二个：

if (answer1 == password || answer2 == password2)

是一样的。试试这个用于第二个 if 语句：

if (answer1 != password || answer2 != password2)

Answer 2

正如其他人所说你使用 char 而不是 std::string

您的代码中有 3 个 cin

cout << "What Is The Game Called? \n";
cin >> game;

cout << "What Is The Username/Email? \n";
cin >> username;

cout << "What Is The Password? \n";
cin >> passwordOnline;

如果你的游戏名称有超过 3 个字符，每个 cin 给 1 char 因为你只读取了 1 个字符，而其他字符保留在 cin 缓冲区中

如果你改变这行

char game;
char username;
char passwordOnline;

到

std::string game;
std::string username;
std::string passwordOnline;

它将正常工作

If statement does not complete code and skips getting user input
