.exe没有显示“按任意键继续...”

Question

In Visual Studio whenever I start without debugging, the .exe file that shows up does not contain the phrase "Press any key to continue..." like it usually does. The screen just has the flashing cursor at the beginning. Is there any easy fix to this? I have commented out some of my code and the phrase shows back up.

This is the code that I have commented out: I have all of the variables and classes declared correctly.

void Maze::addPaths()
{
    Coordinate currentLocation;
    Coordinate startLocation;
    Coordinate endLocation; //not used yet
    std::stack<Coordinate> stack;

    currentLocation.row = (((rand() % HEIGHT) / 2) * 2);
    currentLocation.column = (((rand() % WIDTH) / 2) * 2);

    startLocation = currentLocation;
    grid[currentLocation.row][currentLocation.column] = START;
    player = currentLocation;
    do 
    {
        //drawMaze();
        bool canMoveUp = !(currentLocation.row == 0 || grid[currentLocation.row - 2][currentLocation.column] != WALL);
        bool canMoveDown = !(currentLocation.row == HEIGHT - 1 || grid[currentLocation.row + 2][currentLocation.column] != WALL);
        bool canMoveLeft = !(currentLocation.column == 0 || grid[currentLocation.row][currentLocation.column - 2] != WALL);
        bool canMoveRight = !(currentLocation.column == WIDTH - 1 || grid[currentLocation.row][currentLocation.column + 2] != WALL);

        if (canMoveUp || canMoveDown || canMoveLeft || canMoveRight)
        {
            stack.push(currentLocation);

            //choose random location to dig
            bool moveFound = false;
            while (!moveFound)
            {
                int direction = rand() % 4;
                if (direction == 0 && canMoveUp)
                {
                    moveFound = true;
                    grid[currentLocation.row - 2][currentLocation.column] = PATH;
                    grid[currentLocation.row - 1][currentLocation.column] = PATH;
                    currentLocation.row -= 2;
                }
                else if (direction == 1 && canMoveDown)
                {
                    moveFound = true;
                    grid[currentLocation.row + 2][currentLocation.column] = PATH;
                    grid[currentLocation.row + 1][currentLocation.column] = PATH;
                    currentLocation.row += 2;
                }
                else if (direction == 2 && canMoveLeft)
                {
                    moveFound = true;
                    grid[currentLocation.row][currentLocation.column - 2] = PATH;
                    grid[currentLocation.row][currentLocation.column - 1] = PATH;
                    currentLocation.column -= 2;
                }
                else if (direction == 3 && canMoveRight)
                {
                    moveFound = true;
                    grid[currentLocation.row][currentLocation.column + 2] = PATH;
                    grid[currentLocation.row][currentLocation.column - 2] = PATH;
                    currentLocation.column += 2;
                cout << "yay";
                }
            }
        }
        else if (!stack.empty())
        {
            currentLocation = stack.top();
            stack.pop();
        }
    } while (!stack.empty());
    //addDestinationToGrid();
    cout << "no";
}

Answer 1

On Windows, system("PAUSE"); will prompt a user with the text:

Press any key to continue...

Answer 2

It seems your main do-while loops in endless cycle. How do you initialize grid?

Answer 3

问题最终是我走出了名为grid的数组的边界，而且我还在for循环中混合了行和列。
