C++ How to remove vertical scrollbar? - c++

Question

I am trying to make a fun program where it display random numbers, but I need to remove the scrollbar so it looks more convincing. I managed to make the program full screen but I can't remove the vertical scrollbar. Screenshot
Code:
#include <iostream>
#include <Windows.h>
using namespace std;
int main() {
SetConsoleDisplayMode(GetStdHandle(STD_OUTPUT_HANDLE), CONSOLE_FULLSCREEN_MODE, 0);
int output;
bool done = false;
system("color a");
while (!done) {
output = 1 + (rand() % (int)(1000 - 1 + 1));
cout << output;
}
}

There are many ways, one of them is manipulating the size of the internal buffer of the console to have the same size of the window and then using ShowScrollBar function to remove the scrolls.
#include <iostream>
#include <Windows.h>
#include <WinUser.h>
using namespace std;
int main() {
SetConsoleDisplayMode(GetStdHandle(STD_OUTPUT_HANDLE), CONSOLE_FULLSCREEN_MODE, 0);
HANDLE hstdout = GetStdHandle(STD_OUTPUT_HANDLE);
CONSOLE_SCREEN_BUFFER_INFO csbi;
GetConsoleScreenBufferInfo(hstdout, &csbi);
csbi.dwSize.X = csbi.dwMaximumWindowSize.X;
csbi.dwSize.Y = csbi.dwMaximumWindowSize.Y;
SetConsoleScreenBufferSize(hstdout, csbi.dwSize);
HWND x = GetConsoleWindow();
ShowScrollBar(x, SB_BOTH, FALSE);
int output;
bool done = false;
system("color a");
while (!done) {
output = 1 + (rand() % (int)(1000 - 1 + 1));
cout << output;
}
}
Another way is to rely on conio.h or another C/C++ header/library which implements user interface functions.
