Reading in ascii maze into a 2d array
I am writing code to read in a 7x15 block of text in a file that will be a "maze".
#include <iostream>
#include <fstream>
#include <string>
#include "board.h"
int main()
{
char charBoard[7][15]; //the array we will use to scan the maze and modify it
ifstream loadMaze("maze"); //the fstream we will use to take in a maze
char temp; //our temperary holder of each char we read in
for(int i = 0;i < 7; i++)
{
for(int j = 0; j < 15; j++)
{
temp= loadMaze.get();
charBoard[i][j] = temp;
cout << charBoard[i][j]; //testing
}
cout << endl;
}
return 0;
}
It was my original project, but it didn't work as it kept coming back? for each char, it is read. This is testing the maze with:
#############
#
############ #
#
######### ####
#! #
############
EDIT: Cout prints this:
############# # ############ # # ######### #### #! # #########
Am I not running \ n's?
I have been coding for hours, so I think this is a simple error that I won't catch, which is turning me off right now. Thank!

Try an absolute path like "c: \ MyMazes \ maze".
Throw in ("cd") to see where the current directory is. If you have trouble finding the current directory check out this SO discussion
Here's the complete code - this should display your entire maze (if possible) and your current directory.
char charBoard[7][15]; //the array we will use to scan the maze and modify it
system("cd");
ifstream loadMaze("c:\\MyMazes\\maze"); //the fstream we will use to take in a maze
if(!loadMaze.fail())
{
for(int i = 0;i < 7; i++)
{
// Display a new line
cout<<endl;
for(int j = 0; j < 15; j++)
{
//Read the maze character
loadMaze.get(charBoard[i][j]);
cout << charBoard[i][j]; //testing
}
// Read the newline
loadMaze.get();
}
return 0;
}
return 1;

Is it possible to check the correctness of the extraction from the file: using the good()
APIifstream
for(int j = 0; j < 15; j++)
{
if(!loadMaze.good())
{
cout << "path incorrect";
}
temp= loadMaze.get();
cout << "temp = " << temp << endl; //testing
charBoard[i][j] = temp;
cout << charBoard[i][j]; //testing
}
OR
at the beginning:
ifstream loadMaze("maze");
if(!loadMaze.good())
{
//ERROR
}

Check if the file has opened or not. You can find out by checking if it's good:
http://www.cplusplus.com/reference/iostream/ios/good/
If opening the file fails, try writing the absolute path to the file (C: / Documents and Settings /.../ maze) to see if that works. If so, it's just the wrong file path and you'll have to play with it.
