Question

我正在制作一个基本的暴力程序，我在通过课程使用函数时遇到了麻烦。

注意 - 问题出在＆＃34; Brute Force.cpp.cpp＆＃34;在第21行，我提到了类和函数。

Brute Force.cpp.cpp（我搞砸了名字）（这是主要功能）：

#include "stdafx.h"
#include <iostream>
#include <math.h>
#include <cstdlib>
#include <cmath>
#include <iomanip>
#include <string>

#include "Hidden Password.cpp"
#include "Brute Force.cpp"

using namespace std;

int main()
{
    string bruteforce;


    cout << "Enter the name to brute force \n";

    Hidden_Password::Password_Function(brute_force::brute_force_function());
    return 0;
}

Brute Force.cpp：

#pragma once
#include "stdafx.h"
#include <iostream>
#include <math.h>
#include <cstdlib>
#include <cmath>
#include <iomanip>
#include <string>

using namespace std;

static class brute_force {
    int input;

    public:

        int brute_force_function() {
            for (int i = 0; i >= 10000000000;i++) {
                return i;
            }
        }
    };

隐藏密码.cc：

#pragma once 
#include "stdafx.h"
#include <iostream>
#include <math.h>
#include <cstdlib>
#include <cmath>
#include <iomanip>
#include <string>

#include "Hidden Password.cpp"

using namespace std;

    static class Hidden_Password {
    int private_password = 9265832594;
    int input_password;

    bool correct_password = true;

    public:

            //function
            int Password_Function(int input_password) {
                while (bool correct_password = true) {
                    if (input_password == private_password) {
                        bool correct_password = false;
                        cout << "You got the password \n";
                    }
                }
            }
};

Answer 1

我认为您应该始终根据错误消息开始调试。显然错误是访问静态成员，如错误所示：

1＆gt; c：\ users \ lisa \ documents \ visual studio 2017 \ projects \ brute force.cpp \ brute force.cpp \ brute force.cpp.cpp（23）：错误C2352： 'brute_force :: brute_force_function'：非静态成员的非法调用功能1＆gt; c：\ users \ lisa \ documents \ visual studio 2017 \ projects \ brute force.cpp \ brute force.cpp \ brute force.cpp（17）：注意：见声明 'brute_force :: brute_force_function'

在C ++中，::用于访问静态成员，而不是“常规”成员。静态成员是“每个类一个”，而其他成员则不是，因此只能通过对象访问，并随每个对象一起复制。

因此，您应该使用范围解析运算符::来仅访问静态成员，我建议将int brute_force_function声明为static int brute_force_function。

以下是一些供您参考的资源：https://msdn.microsoft.com/en-us/library/b451xz31.aspx和http://www.cprogramming.com/tutorial/statickeyword.html

我注意到你将类声明为静态，这里是静态类的引用（我不解释自己，因为它超出了问题的范围）：How do you create a static class in C++?和https://codeyarns.com/2012/01/10/c-static-class-definition/

Answer 2

要做的事情：

只有当函数为$v = $_GET['v']; if($v == 1){ header('location: YOUR LINK'); die; } elseif($v == 2){ header('location: YOUR LINK'); die; } elseif($v==3){ header('location: YOUR LINK'); die; } else{ header('location:DEFAULT LINK'); die; }时，范围解析操作::才能像brute_force::brute_force_function()一样使用。

替换static

int brute_force_function() {。

为什么static int brute_force_function() {中的#include Hidden Password.cpp
将Hidden Password.cpp重命名为Brute Force.cpp.cpp

我的基本蛮力计划遇到了麻烦。特别是类的功能
