Here's the txt file:

Question: When I type coordinates at beginning of program, X seams to the Y coordinate and visa versa? eg type X = 1 and Y = 2 shows x - wall and not p - path

In cartesian coordinate notation, x is the horizontal path while y is the vertical path. Using the table:
x = 1 and y = 2 (with zero based indexing) under the cartesian coordinate system would result in 8. However, because C++ arrays are in row-major order, the index of the first dimension is the vertical path (it selects which single array in the array of arrays to use) and the index of the second dimension is the horizontal path (it selects which item in the single array to use). Using the same indices under C++ rules, the result would be 6. You should adjust your logic and assumptions accordingly.
