    arrays and files

    ok here is the code i got
    	fin >> szMap[x][y];
    the problem is well alot of things i think... the file is initialised szMap[37][37]; and the length of the first and only line in map2.txt is 37 characters long and x and y are set to 0 for the time being... besides wondering how to fix the compile errors would this work? and how would i load say


    into array szMap[][] from a file? because the example i have posted only loads one line (that im aware of)

    thx for any and all help

    add the line - x++;
    at the end of your loop...

    and from my understanding y should be zero
       x   0  1  2  3       //x1 points (x1)y0...x2 points to x2(y0)...etc...
    0      L  L   x   e
    1      I  I    x   t
    2      N  N  x   c 
    3      E  E   x   .
    4      1  2   x   \0
    5     \0  \0  \0

    Why this is a "bad thing" is in the FAQ
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
