I am making a C++ Tetris game for my programming class and write now I am working on displaying the bucket and having the pieces drop into the bucket, but I am not yet moving the pieces in the bucket. I am able to build the program successfully, but when the program is ran, nothing is displayed.
Also, I am unsure of how I would be able to animate dropping the pieces into the bucket.
Here is what I have so far.
#include "stdafx.h"
#include <iostream>
#include <Windows.h>
#include <cstdlib>
#include <time.h>

int shapeTopLeftX;
int shapeTopLeftY;
TetrisShape(){
shapeTopLeftX = 6;
shapeTopLeftY = 0;
}

switch(shapeType){

Thank you in advance.

As @ataman has (more-or-less) pointed out in the comments, you aren't actually calling your drawBucket() function in your while loop: you are redeclaring a function named drawBucket(). This is perfectly valid because it's in a different scope; however, it's probably not what you intend.
Change your loop to:
while(gameOver == 0){
drawBucket();
...
}
