    I am trying to finish a maze game i started,
    i cannot seem to implement the idea i have in mind fr this game, am having trouble with what i want,
    i would like to prompt the user to plot their own start and finish points for the maze game, nd for the game to end after they have made their way from their plotted start to finish point,
    i would also like to have a recursive approach to finding this path, also when the user hits the maze wall they should not be able to pass,
    currently the user can pass :snobby:, and my player can only move a limited amount of 3-5 spaces...:sosp:, dont know y...am not the best that y am asking for help..please anyone who can lend a hand and spear some of their time, i would truly be great full. [/mark]

    What the article / tutorials /code snippet does, why it's useful, the problem it solves etc.


    Code:
    ////--a maze game that i would like to (1).prompt the user to enter a start location and a ////finish location 
    ////-----------------------------------(2).Use a recursive approach to find a path in the ////maze from the specified start to the specified finish 
    ////-----------------------------------(3).If a path exists between the two points specified, ////display the path to the screen, otherwise issue an appropriate error message to the user
    ////-----------------------------------(4).If the player meets a wall in maze the player ////cannot pass, i dont understand how to do this.

    You submitted multiple times the same thread as articles and avoid that. I have moved your query into the forum

    -first of all make sure that the user enters valid positions for start and finish points
    positions must be inside the array

    -your for -loops are all wrong

    i---->Rows and not Columns!!!
    j----->Columns and not Rows!!!

    change all for-loops like this
    Code:
    .....
            char Maze[ROW][COLUMN];
            int x;
        
        
        for (int i = 0; i < ROW; i++)
        {
            for (int j = 0; j < COLUMN; j++)
            {
                
                Maze[i][j] = 219;
    .....
    
    -your maze creation algorithm is not good at all.You need to implement a new algorithm

    -when you move inside the maze you must check before you move these:
    1) is the new position a wall?if yes then movement is invalid
    2) is the new position outside the maze?if yes then movement is invalid
    3) is the new position revisited?if yes then movement is invalid
    4) are there any more moves?if no then i ended in a dead end

    -repost your code with changes
