    Option 6 was a joke....
    ....but if only you had kept reading

    Code:
    WINDOWS OPTION: (Credit: Sunlight)
    
    Just call the function clrscr(). Simple as that. 
    
    
    #include <windows.h>
    
    
    
    void clrscr()
    
    {
    
       COORD coordScreen = { 0, 0 };
    
       DWORD cCharsWritten;
    
       CONSOLE_SCREEN_BUFFER_INFO csbi;
    
       DWORD dwConSize;
    
       HANDLE hConsole = GetStdHandle(STD_OUTPUT_HANDLE);
    
    
    
       GetConsoleScreenBufferInfo(hConsole, &csbi);
    
       dwConSize = csbi.dwSize.X * csbi.dwSize.Y;
    
       FillConsoleOutputCharacter(hConsole, TEXT(' '), dwConSize, coordScreen, &cCharsWritten);
    
       GetConsoleScreenBufferInfo(hConsole, &csbi);
    
       FillConsoleOutputAttribute(hConsole, csbi.wAttributes, dwConSize, coordScreen, &cCharsWritten);
    
       SetConsoleCursorPosition(hConsole, coordScreen);
    
    }

    This compiles fine in VC++

    Code:
    #include <iostream>
    using std::cout;
    using std::endl;
    #include <windows.h>
    
    
    
    void clrscr(){
       COORD coordScreen = { 0, 0 };
       DWORD cCharsWritten;
       CONSOLE_SCREEN_BUFFER_INFO csbi;
       DWORD dwConSize;
       HANDLE hConsole = GetStdHandle(STD_OUTPUT_HANDLE);
       GetConsoleScreenBufferInfo(hConsole, &csbi);
       dwConSize = csbi.dwSize.X * csbi.dwSize.Y;
       FillConsoleOutputCharacter(hConsole, TEXT(' '), 
    	   dwConSize, coordScreen, &cCharsWritten);
       GetConsoleScreenBufferInfo(hConsole, &csbi);
       FillConsoleOutputAttribute(hConsole, csbi.wAttributes,
    	   dwConSize, coordScreen, &cCharsWritten);
       SetConsoleCursorPosition(hConsole, coordScreen);
    }
    
    int main(){
    
    	const int nTimes = 3;
    	const int nSpeed = 3000;
    
    	for(int i = 0;i < nTimes;i++){
    		cout << "Few seconds to clear screen!!..Hang on!" << endl;
    		Sleep(nSpeed);
    		clrscr();
    		Sleep(nSpeed);
    	}
    
    	cout << "That's all folks!" << endl;
    
    	return 0;
    }
