C++ rectangle program drawing rects outside of console window - c++

Question

Somewhere in the following code I am missing something. My rects are being drawn outside of the console window and they all need to be within the console. This code is a hack job for a class of mine so I apologize for unnecessary or incorrect code. Sometimes it works but most times it just draws things outside the window. How can I contain the code?
#include "stdafx.h"
#define NOMINMAX
#include <stdio.h>
#include <windows.h>
#include <conio.h>
#include <time.h>
void moveCursor(int x, int y)
{
COORD c = { x,y };
SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE), c);
}
struct Vec2
{
short x, y;
int min, max;
Vec2() : x(rand()% 50), y(rand()%20 ){ }
Vec2(int x, int y) : x(x), y(y) { }
void operator+=(Vec2 v)
{
x += v.x;
y += v.y;
}
};
class Rect
{
Vec2 min, max;
public:
void setMin(Vec2 const & min)
{
this->min = min;
}
void setMax(Vec2 const & max)
{
this->max = max;
}
void setRandom(Rect & r)
{
int x = rand() % 50;
int y = rand() % 20;
int x2 = rand() % 8+3;
int y2 = rand() % 8+3;
Vec2 min(x , y);
r.setMin(min);
Vec2 max(x + x2, y + y2);
r.setMax(max);
}
Rect(int minx, int miny, int maxx, int maxy)
:min(minx, miny), max(maxx, maxy)
{}
Rect() {}
void draw(const char letter) const
{
for (int row = min.y; row < max.y; row++)
{
for (int col = min.x; col < max.x; col++)
{
if (row >= 0 && col >= 0)
{
moveCursor(col, row);
putchar(letter);
}
}
}
}
bool isOverlapping(Rect const & r) const
{
return !(min.x >= r.max.x || max.x <= r.min.x
|| min.y >= r.max.y || max.y <= r.min.y);
}
void translate(Vec2 const & delta)
{
min += (delta);
max += (delta);
}
};
int main()
{
// initialization
srand(time (NULL));
const int Number_of_rects = 5;
Rect *userRect = new Rect(7, 5, 10, 9);
Rect rect[5]{};
int userInput;
do
{
// draw
for (int i = 0; i < Number_of_rects; i++)
{
rect[i].draw('0'+i);
};
moveCursor(0, 0); // re-print instructions
printf("move with 'w', 'a', 's', and 'd'");
userRect->draw('#');
// user input
userInput = _getch();
// update
Vec2 move;
switch (userInput)
{
case 'w': move = Vec2(0, -1); break;
case 'a': move = Vec2(-1, 0); break;
case 's': move = Vec2(0, +1); break;
case 'd': move = Vec2(+1, 0); break;
}
userRect->draw(' '); // un-draw before moving
userRect->translate(move);
} while (userInput != 27); // escape key
delete userRect;
return 0;
}
The '#' are always there, 1 and 0 were drawn but are colliding(different problem) and 2,3,and 4 are being drawn off screen
