Hey guys,
I have written a recursive function mazeTraverse which finds the path of the mouse to find its food which is placed inside the maze. I am given a maze of of 15 rows and 25 columns. Mouse's starting position is (8,1)[eighth row and 1st column] and the food is placed in (5, 10).
In my maze, 'A' represents the way is blocked
' ' represnts an opening
'M' represents starting position for the mouse and 'T' represents the target which is food.
I am supposed to print X which will start moving from starting position to the target. X basically represents the mouse movement from the starting position to the target. I know I need to use recursive function so when mouse find dead end it has to do backtracking.
Here is my header file :
const int ROWS = 15
const int COLS = 25
class MazeMania
{
public:
MazeMania(char maze[ROWS][COLS], int startR, int startC);
void rowCol (int r, int c);
void mazeTraverse( int x, int y);
void printMaze();
void mouseMove();
private:
char mouse[ROWS][COLS];
const static char mouse = 'X'
int row; //starting row
int col; // starting col
};here is my .cpp file
# include "mazeMania.h"
#include "windows.h"
#include <iostream>
using std::cout;
using namespace std;
void MazeMania::rowCol(int r, int c)
{
COORD pos;
pos.X = c;
pos.Y = r;
SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE), pos);
}
Mazemania::MazeMania(char mouse[ROWS][COLS] , int row, int col)
{
for ( int k = 0; k< ROWS; k++)
{
for(int l = 0; l < COLS; l++)
{
this->mouse[k][l] = mouse[k][l];
}
}
printMaze();
this->row = row;
this->col = col;
}
void MazeMania::mazeTraverse(int x, int y)
{
gotoRowCol(x, y);
cout <<" "; // this will delete the mouse (X) previously printed
cout<<mouse;
if (maze[x][y] == 'T')
{
cout<<"Mouse is in target"<<endl;
return;
}
else if ((x + 1, y )!= 'A')
{
mazeTraverse( x+1, col);
rowCol(x+1, y);
cout<<mouse;
return;
}
else if ((x, y+ 1)!= 'A')
{
mazeTraverse(x, y+1);
rowCol(x , y+1);
cout<<mouse;
return;
}
else if ((x-1, y) != 'A')
{
mazeTraverse(x - 1, y);
rowCol(x-1 , y);
cout<<mouse;
return;
}
else if ((x, y -1) != 'A')
{
mazeTraverse( x, y - 1);
rowCol(x, y-1);
cout<<mouse;
return;
}
}
void MazeMania::printMaze()
{
for ( int i = 0; i < ROWS; i++)
{
for (int j = 0; j <COLS; j++)
{
cout<<maze[i][j];
}
cout<<"\n";
}
}
void MazeMania::mouseMove()
{
mazeTraverse(row, col);
}here is what my driver look like :-
char puzzle[ROWS][COLS] = (picture of the maze here)
MazeMania move(puzzle, 8,1)
move.mouseMove()
return 0;compiles fine but X doesn't move instead I get an infinite loop of X where X prints outside the bound of the maze.
I am sure I am messed up in mazeTraverse function. Thank you for your time.
