Thread: Dynamic Two-Dimensional Arrays

Show us the code for loading the dimensions from the file; and then post the file itself.

Its pretty darn absic... I updated the loading of dimensions with get(), and used atoi to make it int. works much better and now only problem is it doesnt load what I want it too(the values come out 0x0, instead of 10x10, doesnt close instant now though)

Set-Size function:

Code:

void testclass::setsize() {
  char *char_length=new char[3];
  char *char_width=new char[3];
  std::ifstream s_size(dat_filename);
  s_size.get(char_length, 2, ' ');
  s_size.get(char_width, 2, ' ');
  s_size.close();
  dat_length=atoi(char_length);
  dat_width=atoi(char_width);
}//testclass setsize func

The file:

Code:

10 10
00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00

The file is pretty basic, just a test right now. Its just that it doesnt load the first two properly.
