Question

​​​​​​This program will make Maze game. Please Help in c++

• Prompt the user for a file that contains the maze. Read it into a two-dimensional array
  • Remember you can use inputStream.get(c) to read the next character from the inputStream. This will read whitespace and non-whitespace characters
  • Don’t forget to read the newline character at the end of each line
• Print the maze to the screen from your array
  • You should include a ‘*’ in your maze to indicate where the user is located. The initial position is the second row, first column
• Prompt the user for a single move
• Print the current location as (x,y) and the location after the move is done as (x,y)
  • For this week, just do the arithmetic, do not worry if the move is bad
  • Note (0, 0) is the upper left corner. X increases to the right and Y increases down
• Use functions as appropriate – you should have more than just main()
• Let small_maze.txt contain the following lines (4 rows, 8 columns):

||||||||
  ||||||
|       
||||||||

Sample Run #1 (bold, underlined text is what the user types):

File? small_maze.txt

||||||||
* ||||||
|       
||||||||
Move (udrlq)? r

(0,1) to (1,1)

Sample Run #2 (bold, underlined text is what the user types):

File? small_maze.txt

||||||||
* ||||||
|       
||||||||
Move (udrlq)? u

(0,1) to (0,0)

Program:

#include<iostream>
#include<fstream>

using namespace std;

//function to read from file
void readFile(char maze[][10], int &m, int &n)
{
char ch, filename[20];
int i = 0,j = 0;
ifstream in;

cout<<"File? ";
cin>>filename;
in.open(filename);

while(in)
{
ch = in.get();
if(ch=='\n')
{
n = i;
i = 0;
j++;
}
else
{
maze[j][i++] = ch;
}
}
m = j;
}

//function to print the maze
void print(char maze[][10], int m, int n)
{
cout<<endl;
for(int i=0; i<m; i++)
{
for(int j=0; j<n; j++)
{
cout<<maze[i][j];
}
cout<<endl;
}
cout<<endl;
}

//main function
int main()
{
char ch;
int i, j, t, m, n;
  
char maze[10][10] = {' '};

//read the file
readFile(maze, m, n);

//initial position is the second row, first column
maze[i=1][j=0] = '*';
  
print(maze, m, n);

while(1)
{
  
   cout<<"Move (udrlq)?";
   cin>>ch;
  
switch(ch)
{
case 'u':
if(i==0)
cout<<"Invalid move!"<<endl;
else
{
   t = i;
   i--;
cout<<"("<<t<<","<<j<<") to ("<<i<<","<<j<<")"<<endl;
}
break;
case 'd':
if(i==m-1)
cout<<"Invalid move!"<<endl;
else
{
   t = i;
   i++;
cout<<"("<<t<<","<<j<<") to ("<<i<<","<<j<<")"<<endl;
               }
               break;
case 'r':
if(j==n-1)
cout<<"Invalid move!"<<endl;
else
{
   t = j;
   j++;
cout<<"("<<i<<","<<t<<") to ("<<i<<","<<j<<")"<<endl;
               }
               break;

case 'l':
if(j==0)
cout<<"Invalid move!"<<endl;
else
{
   t = j;
   j--;
cout<<"("<<i<<","<<t<<") to ("<<i<<","<<j<<")"<<endl;
               }
case 'q':
exit(0);
}
}
return 0;
}

Output:
