    console scrolling

    hello,
    what i am trying to do, is have the user type at the bottom of the console, and print the text at the top example:

    Code:
    #include <iostream>
    #include <string>
    #include <windows.h>
    using namespace std;
    
    
    void gotoxy ( int x, int y )
    {
    	COORD dwCursorPosition = { x, y };
    	SetConsoleCursorPosition ( GetStdHandle ( STD_OUTPUT_HANDLE ), dwCursorPosition );
    }
    
    
    
    int main()
    {
    	int loc=0;
    	string test;
    	while(true){
    		gotoxy(0,23);
    		cout << "type: ";
    		getline(cin, test);
    		gotoxy(0,23);
    		for(int x = test.length()+6; x>0; x--)
    		{
    			cout << ' ';
    		}
    		gotoxy(0,loc);
    		cout << test;
    		loc++;
    	}
    	
    	return 0;
    }
    now this does exactly what i want it to do, untill you have inputted so many times that, it begins to display the text below where your acctually typing.
    so basically when int loc reaches 22 i want to move all the text up one line..?

    if you compile the code, my question may be easier to understand.

    windows,
    MSVC++6

    Code:
    #include <iostream>
    #include <string>
    #include <windows.h>
    using namespace std;
    
    
    void gotoxy ( int x, int y )
    {
    	COORD dwCursorPosition = { x, y };
    	SetConsoleCursorPosition ( GetStdHandle ( STD_OUTPUT_HANDLE ), dwCursorPosition );
    }
    
    
    
    int main()
    {
    	int loc=0;
    	int y = 23;
    	string test;
    	while(true){
    		if (loc == y-1){
    			y++;
    		}
    		gotoxy(0,y);
    		cout << "type: ";
    		getline(cin, test);
    		gotoxy(0,y);
    		for(int x = test.length()+6; x>0; x--)
    		{
    			cout << ' ';
    		}
    		gotoxy(0,loc);
    		cout << test;
    		loc++;

    I cover scrolling horizontally, vertically and even diagonally in my console tutorials, this topic is in part 6, but I recommend you start from the beginning, here.
    Wave upon wave of demented avengers march cheerfully out of obscurity unto the dream.

    You can implement text windows in your code to create scrolling in separate portions of the screen. Use adrian's code for scrolling but place the code into your window class. That way each window on screen can scroll vertically, horizontall, and even diagonally.
