I'm trying to make a certain word do one command. like "/list" would open up a list.

#include <iostream>
#include <cstdlib>

using namespace std;
#include <iostream>
#include <cstdlib>

using namespace std;

// note C:\Dev-Cpp\include\c++\3.4.2\iosfwd:62 candidates are: std::basic_istream<char,> >& std::basic_istream<char,> >::operator=(const std::basic_istream<char,> >&) 
//16 C:\Dev-Cpp\Untitled1.cpp no match for 'operator=' in '(&std::cin)->std::basic_istream<_CharT, _Traits>::operator>> [with _CharT = char, _Traits = std::char_traits<char>](((int&)(&list))) = 1' 

int main()
{
    system("cls");
    system("title Command Game!");
    
    int list;
    cout << "Type ''list'' for options. \n\n\n\n\n\n\n\n\n \n";
    cin >> list;
    if(list == 1); 
   {
            system("color a");
       cout << "List: 1. Crack The Code,   2. Exit,     3. Cheats - - - - \n \n \n \n        ";
       int main;
       }
       
       int Code_Command();
       int code;
       cout << "New Code?";
       cin >> code;
       if(code == 1);
       {
               int Exit_Command;
               int level1;
               }
       
}
int Exit_Command()
{
    system("cls");
    int exit;
    cout << "Good-Bye!";
    cin >> exit;

    if(exit == 1);
    {
            system("PAUSE");
            return 0;
            }
            }
    
int Cheat_Command()
{
 int cheats;
 cout << "Cheater. :D";
 cin >> cheats;
 
 if(cheats == 1);
 {
           system("cmd");
 system("PAUSE");
 return 0;
 int level1;
}
}

 int level1();
 {
 system("title Level 1");
 cout << "Level 1: EASY.    Most people know this word from Marry Poppin's: ";
 cin >> supercalafragilisticexpealidocious;
 if(supercalafragilisticexpealidocious == 1);
 {
                                       int level2;
                                       }
                                       }
 int level2();
 {
 system("title Level 2");
 cout << "Level 2: MEDIUM.    A giant, well known hacking group of 2010 with no personalities known."
 cin >> anonymous;
 if(anonymous == 1);
 {
              int level3;
              }
}
