   Why does this throw an access violation segmentation fault ?
  Basically, whenever I compile with a single thing changed in these few lines of code, I get that in the debugger (Dev-C++): My map is defined like this:int mizzap [ROWS][COLS];This one Works:  infile = fopen(ifilename,"r");    for(c = 0; c < ROWS; c++)    {  fscanf(infile,"%d",mizzap [c]);    }    fclose(infile);This one doesn't:   infile = fopen(ifilename,"r");    for(c = 0; c < ROWS; c++)    {  fscanf(infile,"%d",mizzap [r][c]);    }    fclose(infile);Thanks in advance for the help!   
  When you pass arguments to fscanf(), you're supposed to use the address of the variable, not the variable itself. This line:fscanf(infile,"%d",mizzap [r][c]);should be:fscanf(infile,"%d", &(mizzap[r][c]));Though if you're using C++ I'd recommend using the stream IO instead.   ;  How big is mizzap ?  Is it even a 2D array ?Where the hell does 'r' come from ?Why is c compared to the number of rows ?  I suppose you want r to represent the row and c the column ?   ;  r indicates rows, and I'm sorry that I forgot to mention that Mizzap is indeed an array, personally, I like the name :D.And also, big thanks SiCrane, I dont know how I overlooked that too.  And I am using C, just for reference.
