2-dim array display output for matching game

[CuriousGeorge]

I am creating a matching game, using US States and a 2-dim array.

As you can see, when the below code runs, some of the grid tiles appear offset, and when selected by pressing spacebar, do not appear.

Any advice on why it is misbehaving is greatly appreciated!

Here is the .h file:

#include "stdafx.h"
#include <iostream>
#include <cstdlib>
#include <ctime>
#include <string>
#include <windows.h>
using namespace std;

int locX, locY;
int select4[4][4] = { 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 };
int select6[6][6] = { 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
0, 0, 0, 0 };
int select8[8][8] = { 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 };

and then the main function file:

#include "Project.h"
using namespace std;

	Game.chose6();
	return 0;

Honestly, I just very quickly read your post, but could it be caused because the font is not of consistent size?

[CuriousGeorge]

Sorry I'm not quite sure I understand: how would I go about correcting the font?

I also suspect that the below functions, responsible for grid output/navigation, may be the source of the issue:

void showGrid6(){ // Output current grid
		system("cls");
		cout << "   1  2  3  4  5  6" << endl << endl;
		for (int y = 0; y<6; y++){
			cout << y + 1 << "  ";
			for (int x = 0; x<6; x++){
				if (move6[x][y].getFaceUp() == true){ // show the state
					cout << move6[x][y].getVal() << " ";
				}
				else{ // facing down, can't see
					cout << (char) 177 << "  ";
				}
			}
			cout << endl;
			cout << "   ";
			for (int x = 0; x<6; x++){
				if (select6[x][y] == 1){ // selector arrow at coord
					cout << (char) 94 << "  ";
				}
				else{ //no arrow at coord
					cout << "   ";
				}
			}
			cout << endl;
		}
		cout << endl;
	}

	void userMoves6(){ //move pointer
		while (1){
			while (1){
				if (GetAsyncKeyState(VK_UP) & 1){ // UP
					if ((locY - 1) < 0){ // If out of bounds
						locY = 5;
					}
					else{
						locY--;
					}
					break;
				}
				if (GetAsyncKeyState(VK_DOWN) & 1){ // DOWN
					if ((locY + 1) > 5){ // If out of bounds
						locY = 0;
					}
					else{
						locY++;
					}
					break;
				}
				if (GetAsyncKeyState(VK_LEFT) & 1){ // LEFT
					if ((locX - 1) < 0){ // If out of bounds
						locX = 5;
					}
					else{
						locX--;
					}
					break;
				}
				if (GetAsyncKeyState(VK_RIGHT) & 1){ // RIGHT
					if ((locX + 1) > 5){ // If out of bounds
						locX = 0;
					}
					else{
						locX++;
					}
					break;
				}
				if ((GetAsyncKeyState(VK_SPACE) & 1)){ // SPACE = flips tile pointed at
					if (move6[locX][locY].getFaceUp() == true){ // if pick already matched tile
						cout << "You can't select this tile again!" << endl << endl;
						continue;
					}
					else{
						move6[locX][locY].turnTile();
						return;
					}
				}
			}
			// following every key pressed
			for (int y = 0; y<6; y++){
				for (int x = 0; x<6; x++){
					select6[x][y] = 0; // Clear array
				}
			}
			select6[locX][locY] = 1; // Sets array at right position
			showGrid6(); // Updates grid
		}
	}

Some screenshots of the problem will probably help me find your problem. It's a lot of code to look through with no immediately obvious cause (to me at least) for this error. In particular, to see what

some of the grid tiles appear offset

is causing this.
